* net: Properly define functions with no parametersBen Hutchings2012-07-111-1/+1
| | | | | | | | Defining a function with no parameters as 'T foo()' is the deprecated K&R style, and is not strictly equivalent to defining it as 'T foo(void)'. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | For RTL8111G, the settings of phy and firmware are replaced with ocp functions. r8168g_mdio_{write / read} redirects the relative settings to suitable ocp functions. A per-device variable is needed to evaluate the real address of ocp functions. rtl_writephy(tp, 0x1f, xxxx) is dedicated to keeping said variable up-to-date.

* | net/fsl_pq_mdio: use spin_event_timeout() to poll the indicator registerTimur Tabi2012-07-101-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | Macro spin_event_timeout() was designed for simple polling of hardware registers with a timeout, so use it when we poll the MIIMIND register. This allows us to return an error code instead of polling indefinitely. Note that PHY_INIT_TIMEOUT is a count of loop iterations, so we can't use it for spin_event_timeout(), which asks for microseconds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least in the i.MX series, the flexcan contrller divides into ver_3 and ver_10, current driver is for ver_3 controller. i.MX6 has ver_10 controller, it has more reigsters than ver_3 has. The rxfgmask (Rx FIFO Global Mask) register is one of the new added. Its reset value is 0xffffffff, this means ID Filter Table must be checked when receive a packet, but the driver is designed to accept everything during the chip start, we need to clear this register to follow this design. Use the data entry of the struct of_device_id to point chip specific info, we can set hardware version for each platform.

This driver needs to push 4 bytes in front of frame (packet_len) and maybe add 4 bytes after the end (if padlen is 4) So it should set needed_headroom & needed_tailroom to avoid copies. But its not enough, because many packets are cloned before entering asix_tx_fixup() and this driver use skb_cloned() as a lazy way to check if it can push and put additional bytes in frame. Avoid skb_copy_expand() expensive call, using following rules : - We are allowed to push 4 bytes in headroom if skb_header_cloned() is false (and if we have 4 bytes of headroom) - We are allowed to put 4 bytes at tail if skb_cloned() is false (and if we have 4 bytes of tailroom) TCP packets for example are cloned, but skb_header_release() was called in tcp stack, allowing us to use headroom for our needs.

* | {NET, IB}/mlx4: Add device managed flow steering firmware APIHadar Hen Zion2012-07-0813-76/+655
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is modified to support three operation modes. If supported by firmware use the device managed flow steering API, that which we call device managed steering mode. Else, if the firmware supports the B0 steering mode use it, and finally, if none of the above, use the A0 steering mode. When the steering mode is device managed, the code is modified such that L2 based rules set by the mlx4_en driver for Ethernet unicast and multicast, and the IB stack multicast attach calls done through the mlx4_ib driver are all routed to use the device managed API. When attaching rule using device managed flow steering API, the firmware returns a 64 bit registration id, which is to be provided during detach. Currently the firmware is always programmed during HCA initialization to use standard L2 hashing. Future work should be done to allow configuring the flow-steering hash function with common, non proprietary means.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of checking the firmware supported steering mode in various places in the code, add a dedicated field in the mlx4 device capabilities structure which is written once during the initialization flow and read across the code. This also set the grounds for add new steering modes. Currently two modes are supported, and are named after the ConnectX HW versions A0 and B0. A0 steering uses mac_index, vlan_index and priority to steer traffic into pre-defined range of QPs. B0 steering uses Ethernet L2 hashing rules and is enabled only if the firmware supports both unicast and multicast B0 steering, The current steering modes are relevant for Ethernet traffic only, such that Infiniband steering remains untouched.

* | net/mlx4_en: Re-design multicast attachments flowYevgeny Petrilin2012-07-082-35/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, for every change in the net device multicast list, the driver detaches all the addresses from the HW device, and then attaches the updated list. This behavior is wrong from two aspects: first, it causes a load of firmware commands and second, there is period of time where the correct addresses are not attached, which turned into packet loss. To improve - a copy of the multicast list is saved by the driver. For every change in the multicast list, the multicast list copy is used to find the delta between those two lists and add or remove multicast addresses as needed.

Several buffer overflows in NCI layer from Dan Rosenberg, and release sock OOPS'er fix from Eric Dumazet. 5) Fix WEP handling ath9k, we started using a bit the chip provides to indicate undecrypted packets but that bit turns out to be unreliable in certain configurations. Fix from Felix Fietkau. 6) Fix Kconfig dependency bug in wlcore, from Randy Dunlap. 7) New USB IDs for rtlwifi driver from Larry Finger. 8) Fix crashes in qmi_wwan usbnet driver when disconnecting, from Bjørn Mork. 9) Gianfar driver programs coalescing settings properly in single queue mode, but does not do so in multi-queue mode. Fix from Claudiu Manoil. 10) Missing module.h include in davinci_cpdma.c, from Daniel Mack. 11) Need dummy handler for IPSET_CMD_NONE otherwise we crash in ipset if we get this via nfnetlink, fix from Tomasz Bursztyka. 12) Missing RCU unlock in nfnetlink error path, also from Tomasz. 13) Fix divide by zero in igbvf when the user tries to set an RX coalescing value of 0 usecs, from Mitch A Williams. 14) We can process SCTP sacks for the wrong transport, oops. Fix from Neil Horman. 15) Remove hw IP payload checksumming from e1000e driver. This has zery value in our stack, and turning it on creates a very unintuitive restriction for users when using jumbo MTUs. Specifically, when IP payload checksums are on you cannot use both receive hashing offload and jumbo MTU.

Users currently must disable jumbos when receive hashing offload is enabled, or vice versa, because of this incompatibility. Since testing has shown that IP payload checksum does not provide any real benefit, just remove it so that there is no longer a choice between jumbos or receive hashing offload but not both as done in other Intel GbE drivers (e.g. e1000, igb). Also, add a missing check for IP checksum error reported by the hardware; let the stack verify the checksum when this happens.

| * | | | | floppy: cancel any pending fd_timeouts before adding a new oneLinus Torvalds2012-07-041-0/+1

However, the "del_timer(&fd_timeout)" was lost in the process, and any previous pending timeouts would stay active when we then re-queued the timeout. This resulted in the floppy probe sequence having a (stale) 20s timeout rather than the intended 3s timeout, and thus made booting with the floppy driver (but no actual floppy controller) take much longer than it should. Of course, there's little reason for most people to compile the floppy driver into the kernel at all, which is why most people never noticed. Canceling the delayed work where we used to do the del_timer() fixes the issue, and makes the floppy probing use the proper new timeout instead. The three second timeout is still very wasteful, but better than the 20s one.
