Supported - * adapters include: - * - * DEC FDDIcontroller/TURBOchannel (DEFTA) - * DEC FDDIcontroller/EISA (DEFEA) - * DEC FDDIcontroller/PCI (DEFPA) - * - * The original author: - * LVS Lawrence V. Stefani <lstefani@yahoo.com> - * - * Maintainers: - * macro Maciej W. Rozycki <macro@linux-mips.org> - * - * Credits: - * I'd like to thank Patricia Cross for helping me get started with - * Linux, David Davies for a lot of help upgrading and configuring - * my development system and for answering many OS and driver - * development questions, and Alan Cox for recommendations and - * integration help on getting FDDI support into Linux. LVS - * - * Driver Architecture: - * The driver architecture is largely based on previous driver work - * for other operating systems. The upper edge interface and - * functions were largely taken from existing Linux device drivers - * such as David Davies' DE4X5.C driver and Donald Becker's TULIP.C - * driver. - * - * Adapter Probe - - * The driver scans for supported EISA adapters by reading the - * SLOT ID register for each EISA slot and making a match - * against the expected value. - * - * Bus-Specific Initialization - - * This driver currently supports both EISA and PCI controller - * families. While the custom DMA chip and FDDI logic is similar - * or identical, the bus logic is very different. After - * initialization, the only bus-specific differences is in how the - * driver enables and disables interrupts. Other than that, the - * run-time critical code behaves the same on both families. - * It's important to note that both adapter families are configured - * to I/O map, rather than memory map, the adapter registers. - * - * Driver Open/Close - - * In the driver open routine, the driver ISR (interrupt service - * routine) is registered and the adapter is brought to an - * operational state. In the driver close routine, the opposite - * occurs; the driver ISR is deregistered and the adapter is - * brought to a safe, but closed state. Users may use consecutive - * commands to bring the adapter up and down as in the following - * example: - * ifconfig fddi0 up - * ifconfig fddi0 down - * ifconfig fddi0 up - * - * Driver Shutdown - - * Apparently, there is no shutdown or halt routine support under - * Linux. This routine would be called during "reboot" or - * "shutdown" to allow the driver to place the adapter in a safe - * state before a warm reboot occurs. To be really safe, the user - * should close the adapter before shutdown (eg. ifconfig fddi0 down) - * to ensure that the adapter DMA engine is taken off-line. However, - * the current driver code anticipates this problem and always issues - * a soft reset of the adapter at the beginning of driver initialization. - * A future driver enhancement in this area may occur in 2.1.X where - * Alan indicated that a shutdown handler may be implemented. - * - * Interrupt Service Routine - - * The driver supports shared interrupts, so the ISR is registered for - * each board with the appropriate flag and the pointer to that board's - * device structure. This provides the context during interrupt - * processing to support shared interrupts and multiple boards. - * - * Interrupt enabling/disabling can occur at many levels. At the host - * end, you can disable system interrupts, or disable interrupts at the - * PIC (on Intel systems). Across the bus, both EISA and PCI adapters - * have a bus-logic chip interrupt enable/disable as well as a DMA - * controller interrupt enable/disable. - * - * The driver currently enables and disables adapter interrupts at the - * bus-logic chip and assumes that Linux will take care of clearing or - * acknowledging any host-based interrupt chips. - * - * Control Functions - - * Control functions are those used to support functions such as adding - * or deleting multicast addresses, enabling or disabling packet - * reception filters, or other custom/proprietary commands. Presently, - * the driver supports the "get statistics", "set multicast list", and - * "set mac address" functions defined by Linux. A list of possible - * enhancements include: - * - * - Custom ioctl interface for executing port interface commands - * - Custom ioctl interface for adding unicast addresses to - * adapter CAM (to support bridge functions). - * - Custom ioctl interface for supporting firmware upgrades. - * - * Hardware (port interface) Support Routines - - * The driver function names that start with "dfx_hw_" represent - * low-level port interface routines that are called frequently. They - * include issuing a DMA or port control command to the adapter, - * resetting the adapter, or reading the adapter state. Since the - * driver initialization and run-time code must make calls into the - * port interface, these routines were written to be as generic and - * usable as possible. - * - * Receive Path - - * The adapter DMA engine supports a 256 entry receive descriptor block - * of which up to 255 entries can be used at any given time. The - * architecture is a standard producer, consumer, completion model in - * which the driver "produces" receive buffers to the adapter, the - * adapter "consumes" the receive buffers by DMAing incoming packet data, - * and the driver "completes" the receive buffers by servicing the - * incoming packet, then "produces" a new buffer and starts the cycle - * again. Receive buffers can be fragmented in up to 16 fragments - * (descriptor entries). For simplicity, this driver posts - * single-fragment receive buffers of 4608 bytes, then allocates a - * sk_buff, copies the data, then reposts the buffer. To reduce CPU - * utilization, a better approach would be to pass up the receive - * buffer (no extra copy) then allocate and post a replacement buffer. - * This is a performance enhancement that should be looked into at - * some point. - * - * Transmit Path - - * Like the receive path, the adapter DMA engine supports a 256 entry - * transmit descriptor block of which up to 255 entries can be used at - * any given time. Transmit buffers can be fragmented in up to 255 - * fragments (descriptor entries). This driver always posts one - * fragment per transmit packet request. - * - * The fragment contains the entire packet from FC to end of data. - * Before posting the buffer to the adapter, the driver sets a three-byte - * packet request header (PRH) which is required by the Motorola MAC chip - * used on the adapters. The PRH tells the MAC the type of token to - * receive/send, whether or not to generate and append the CRC, whether - * synchronous or asynchronous framing is used, etc. Since the PRH - * definition is not necessarily consistent across all FDDI chipsets, - * the driver, rather than the common FDDI packet handler routines, - * sets these bytes. - * - * To reduce the amount of descriptor fetches needed per transmit request, - * the driver takes advantage of the fact that there are at least three - * bytes available before the skb->data field on the outgoing transmit - * request. This is guaranteed by having fddi_setup() in net_init.c set - * dev->hard_header_len to 24 bytes. 21 bytes accounts for the largest - * header in an 802.2 SNAP frame. The other 3 bytes are the extra "pad" - * bytes which we'll use to store the PRH. - * - * There's a subtle advantage to adding these pad bytes to the - * hard_header_len, it ensures that the data portion of the packet for - * an 802.2 SNAP frame is longword aligned. Other FDDI driver - * implementations may not need the extra padding and can start copying - * or DMAing directly from the FC byte which starts at skb->data. Should - * another driver implementation need ADDITIONAL padding, the net_init.c - * module should be updated and dev->hard_header_len should be increased. - * NOTE: To maintain the alignment on the data portion of the packet, - * dev->hard_header_len should always be evenly divisible by 4 and at - * least 24 bytes in size. - * - * Modification History: - * Date Name Description - * 16-Aug-96 LVS Created. - * 20-Aug-96 LVS Updated dfx_probe so that version information - * string is only displayed if 1 or more cards are - * found. Changed dfx_rcv_queue_process to copy - * 3 NULL bytes before FC to ensure that data is - * longword aligned in receive buffer. - * 09-Sep-96 LVS Updated dfx_ctl_set_multicast_list to enable - * LLC group promiscuous mode if multicast list - * is too large. LLC individual/group promiscuous - * mode is now disabled if IFF_PROMISC flag not set. - * dfx_xmt_queue_pkt no longer checks for NULL skb - * on Alan Cox recommendation.

Stefani <lstefani@yahoo.com> + * + * Maintainers: + * macro Maciej W. Rozycki <macro@linux-mips.org> + * + * Credits: + * I'd like to thank Patricia Cross for helping me get started with + * Linux, David Davies for a lot of help upgrading and configuring + * my development system and for answering many OS and driver + * development questions, and Alan Cox for recommendations and + * integration help on getting FDDI support into Linux. LVS + * + * Driver Architecture: + * The driver architecture is largely based on previous driver work + * for other operating systems. The upper edge interface and + * functions were largely taken from existing Linux device drivers + * such as David Davies' DE4X5.C driver and Donald Becker's TULIP.C + * driver. + * + * Adapter Probe - + * The driver scans for supported EISA adapters by reading the + * SLOT ID register for each EISA slot and making a match + * against the expected value. + * + * Bus-Specific Initialization - + * This driver currently supports both EISA and PCI controller + * families. While the custom DMA chip and FDDI logic is similar + * or identical, the bus logic is very different. After + * initialization, the only bus-specific differences is in how the + * driver enables and disables interrupts. Other than that, the + * run-time critical code behaves the same on both families. + * It's important to note that both adapter families are configured + * to I/O map, rather than memory map, the adapter registers. + * + * Driver Open/Close - + * In the driver open routine, the driver ISR (interrupt service + * routine) is registered and the adapter is brought to an + * operational state. In the driver close routine, the opposite + * occurs; the driver ISR is deregistered and the adapter is + * brought to a safe, but closed state. Users may use consecutive + * commands to bring the adapter up and down as in the following + * example: + * ifconfig fddi0 up + * ifconfig fddi0 down + * ifconfig fddi0 up + * + * Driver Shutdown - + * Apparently, there is no shutdown or halt routine support under + * Linux. This routine would be called during "reboot" or + * "shutdown" to allow the driver to place the adapter in a safe + * state before a warm reboot occurs. To be really safe, the user + * should close the adapter before shutdown (eg. ifconfig fddi0 down) + * to ensure that the adapter DMA engine is taken off-line. However, + * the current driver code anticipates this problem and always issues + * a soft reset of the adapter at the beginning of driver initialization. + * A future driver enhancement in this area may occur in 2.1.X where + * Alan indicated that a shutdown handler may be implemented. + * + * Interrupt Service Routine - + * The driver supports shared interrupts, so the ISR is registered for + * each board with the appropriate flag and the pointer to that board's + * device structure. This provides the context during interrupt + * processing to support shared interrupts and multiple boards. + * + * Interrupt enabling/disabling can occur at many levels. At the host + * end, you can disable system interrupts, or disable interrupts at the + * PIC (on Intel systems). Across the bus, both EISA and PCI adapters + * have a bus-logic chip interrupt enable/disable as well as a DMA + * controller interrupt enable/disable. + * + * The driver currently enables and disables adapter interrupts at the + * bus-logic chip and assumes that Linux will take care of clearing or + * acknowledging any host-based interrupt chips. + * + * Control Functions - + * Control functions are those used to support functions such as adding + * or deleting multicast addresses, enabling or disabling packet + * reception filters, or other custom/proprietary commands. Presently, + * the driver supports the "get statistics", "set multicast list", and + * "set mac address" functions defined by Linux. A list of possible + * enhancements include: + * + * - Custom ioctl interface for executing port interface commands + * - Custom ioctl interface for adding unicast addresses to + * adapter CAM (to support bridge functions). + * - Custom ioctl interface for supporting firmware upgrades. + * + * Hardware (port interface) Support Routines - + * The driver function names that start with "dfx_hw_" represent + * low-level port interface routines that are called frequently. They + * include issuing a DMA or port control command to the adapter, + * resetting the adapter, or reading the adapter state. Since the + * driver initialization and run-time code must make calls into the + * port interface, these routines were written to be as generic and + * usable as possible. + * + * Receive Path - + * The adapter DMA engine supports a 256 entry receive descriptor block + * of which up to 255 entries can be used at any given time. The + * architecture is a standard producer, consumer, completion model in + * which the driver "produces" receive buffers to the adapter, the + * adapter "consumes" the receive buffers by DMAing incoming packet data, + * and the driver "completes" the receive buffers by servicing the + * incoming packet, then "produces" a new buffer and starts the cycle + * again. Receive buffers can be fragmented in up to 16 fragments + * (descriptor entries). For simplicity, this driver posts + * single-fragment receive buffers of 4608 bytes, then allocates a + * sk_buff, copies the data, then reposts the buffer. To reduce CPU + * utilization, a better approach would be to pass up the receive + * buffer (no extra copy) then allocate and post a replacement buffer. + * This is a performance enhancement that should be looked into at + * some point. + * + * Transmit Path - + * Like the receive path, the adapter DMA engine supports a 256 entry + * transmit descriptor block of which up to 255 entries can be used at + * any given time. Transmit buffers can be fragmented in up to 255 + * fragments (descriptor entries). This driver always posts one + * fragment per transmit packet request. + * + * The fragment contains the entire packet from FC to end of data. + * Before posting the buffer to the adapter, the driver sets a three-byte + * packet request header (PRH) which is required by the Motorola MAC chip + * used on the adapters. The PRH tells the MAC the type of token to + * receive/send, whether or not to generate and append the CRC, whether + * synchronous or asynchronous framing is used, etc. Since the PRH + * definition is not necessarily consistent across all FDDI chipsets, + * the driver, rather than the common FDDI packet handler routines, + * sets these bytes. + * + * To reduce the amount of descriptor fetches needed per transmit request, + * the driver takes advantage of the fact that there are at least three + * bytes available before the skb->data field on the outgoing transmit + * request. This is guaranteed by having fddi_setup() in net_init.c set + * dev->hard_header_len to 24 bytes. 21 bytes accounts for the largest + * header in an 802.2 SNAP frame. The other 3 bytes are the extra "pad" + * bytes which we'll use to store the PRH. + * + * There's a subtle advantage to adding these pad bytes to the + * hard_header_len, it ensures that the data portion of the packet for + * an 802.2 SNAP frame is longword aligned. Other FDDI driver + * implementations may not need the extra padding and can start copying + * or DMAing directly from the FC byte which starts at skb->data. Should + * another driver implementation need ADDITIONAL padding, the net_init.c + * module should be updated and dev->hard_header_len should be increased. + * NOTE: To maintain the alignment on the data portion of the packet, + * dev->hard_header_len should always be evenly divisible by 4 and at + * least 24 bytes in size. + * + * Modification History: + * Date Name Description + * 16-Aug-96 LVS Created. + * 20-Aug-96 LVS Updated dfx_probe so that version information + * string is only displayed if 1 or more cards are + * found. Changed dfx_rcv_queue_process to copy + * 3 NULL bytes before FC to ensure that data is + * longword aligned in receive buffer. + * 09-Sep-96 LVS Updated dfx_ctl_set_multicast_list to enable + * LLC group promiscuous mode if multicast list + * is too large. LLC individual/group promiscuous + * mode is now disabled if IFF_PROMISC flag not set. + * dfx_xmt_queue_pkt no longer checks for NULL skb + * on Alan Cox recommendation. Added node address + * override support. + * 12-Sep-96 LVS Reset current address to factory address during + * device open.
