* cris build fixes: update eth_v10.c ethernet driverJesper Nilsson2007-11-151-152/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New (updated) version of ethernet driver for cris v10. - First steps to simplify and make the MII code more similar between the etrax100 and etraxfs ports. - Start the transmit queue before enabling tx interrupts to avoid race with the first frame. - Flip the comparition statement to stick to physical addresses to avoid phys_to_virt mapping a potential null pointer. This was not an error but the change simplifies debugging of address-space mappings. - Made myPrevRxDesc local to e100_rx since it was only used there. Fixed out of memory handling in e100_rx. If dev_alloc_skb() fails persistently the system is hosed anyway but at least it won't loop in an interrupt handler. - Correct some code formatting issues. - Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

* [TG3]: Increase the PCI MRRSMatt Carlson2007-11-131-1/+7
| | | | | | | | | | | Previous devices hardcoded the PCI Maximum Read Request Size to 4K. To better comply with the PCI spec, the hardware now defaults the MRRS to 512 bytes. This will yield poor driver performance if left untouched. This patch increases the MRRS to 4K on driver initialization.

* [TG3]: Fix nvram selftest failuresMatt Carlson2007-11-132-6/+38
| | | | | | | | | | | | | Newer devices contain bootcode in the chip's private ROM area. This bootcode is called selfboot. Selfboot can be patched in the device's NVRAM and the patches can have several formats. In one particular format, the checksum calculation needs to be slightly modified. This patch adjusts the NVRAM test code for that case, and add support for the missing formats.

* [TG3]: 5784 / 5764 GPHY power down fixMatt Carlson2007-11-132-3/+32
| | | | | | | | | | | | | | 5784 and 5764 devices fail to link / pass traffic after one load / unload cycle. This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

* [TG3]: Fix 5761 PXEboot crashMatt Carlson2007-11-131-23/+23
| | | | | | | | | | | | | | | | When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

* [SUNGEM]: Fix suspend regression due to NAPI changes.Johannes Berg2007-11-131-6/+5
| | | | | | | | | | | | | | | | | | Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

* bonding: don't validate address at device openJay Vosburgh2007-11-101-0/+1
| | | | | | | | | | | | | | The standard validate_addr handler refuses to accept the all zeroes address as valid. However, it's common historical practice for the bonding master to be configured up prior to having any slaves, at which time the master will have a MAC address of all zeroes. Resolved by setting the dev->validate_addr to NULL. The master still can't end up with an invalid address, as the set_mac_address function tests for validity.
