2010-10-18bnx2x: Optimized the branching in the bnx2x_rx_int()Vladislav Zolotarov
Optimized the branching in the bnx2x_rx_int() based on the fact that FP CQE will always have at least one of START or STOP flags set, so if not both bits are set and START bit is not set, then it's a STOP bit that is set.

2010-10-18ns83820: spin_lock_irq() => spin_lock()Dan Carpenter
This is essentially cosmetic. At this point the IRQs are already disabled because we called spin_lock_irq(&dev->rx_info.lock). The real bug here was fixed back in 2006 in 3a10ccebe: "[PATCH] lock validator: fix ns83820.c irq-flags bug". Prior to that patch, it was a "spin_lock_irq is not nestable" type bug. The 2006 patch changes the unlock to not re-enable IRQs, which eliminates the potential deadlock. But this bit was missed. We should change the lock function as well so it balances nicely.

2010-10-17tg3: Report invalid link from tg3_get_settings()Matt Carlson
Currently the tg3 driver leaves the speed and duplex fields uninitialized in tg3_get_settings() if the device is not up. This can lead to some strange deductions in certain versions of ethtool. When the device is up and the link is down, the driver reports SPEED_INVALID and DUPLEX_INVALID for these fields. This patch makes the presentation consistent by returning SPEED_INVALID and DUPLEX_INVALID when the device has not been brought up as well.

2010-10-16r8169: use 50% less ram for RX ringEric Dumazet
Using standard skb allocations in r8169 leads to order-3 allocations (if PAGE_SIZE=4096), because NIC needs 16383 bytes, and skb overhead makes this bigger than 16384 -> 32768 bytes per "skb" Using kmalloc() permits to reduce memory requirements of one r8169 nic by 4Mbytes. (256 frames * 16Kbytes). This is fine since a hardware bug requires us to copy incoming frames, so we build real skb when doing this copy.

2010-10-14cnic: Decouple uio close from cnic shutdownMichael Chan
During cnic shutdown, the original driver code requires userspace to close the uio device within a few seconds. This doesn't always happen as the userapp may be hung or otherwise take a long time to close. The system may crash when this happens. We fix the problem by decoupling the uio structures from the cnic structures during cnic shutdown. We do not unregister the uio device until the cnic driver is unloaded. This eliminates the unreliable wait loop for uio to close. All uio structures are kept in a linked list. If the device is shutdown and later brought back up again, the uio strcture will be found in the linked list and coupled back to the cnic structures.
