2006-08-19[PATCH] build fixes: smc91xDavid Brownell
Unclear how these bugs arrived, presumably from incorrect cleanup of the 16-bit-only paths, but smc91x wouldn't build for OMAP.

2006-08-19[PATCH] via-rhine: add option avoid_D3 (work around broken BIOSes)Roger Luethi
It looks like broken BIOSes controlling Rhine chips will remain in use in significant numbers; such systems fail to come up via PXE after they have been put into D3 (power-saving) mode. This patch adds a module option for disabling the call that puts the chip to sleep.

2006-08-17[BNX2]: Fix tx race condition.Michael Chan
Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int() similar to the one in tg3 discovered by Herbert Xu: CPU0 CPU1 bnx2_start_xmit() if (tx_ring_full) { tx_lock bnx2_tx() if (!netif_queue_stopped) netif_stop_queue() if (!tx_ring_full) update_tx_ring netif_wake_queue() tx_unlock } Even though tx_ring is updated before the if statement in bnx2_tx_int() in program order, it can be re-ordered by the CPU as shown above. This scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has just freed up the entire tx_ring. The possibility of this happening should be very rare though. The following changes are made, very much identical to the tg3 fix: 1. Add memory barrier to fix the above race condition. 2. Eliminate the private tx_lock altogether and rely solely on netif_tx_lock. This eliminates one spinlock in bnx2_start_xmit() when the ring is full. 3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling netif_wake_queue(). 4. Add memory barrier to bnx2_tx_avail(). 5. Add bp->tx_wake_thresh which is set to half the tx ring size. 6. Check for the full wake queue condition before getting netif_tx_lock in tg3_tx(). This reduces the number of unnecessary spinlocks when the tx ring is full in a steady-state condition.
