2008-06-12net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller
If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

2008-05-02bnx2: Update RV2P firmware for 5709.Michael Chan
The new RV2P firmware fixes 2 issues: 1. The jumbo rx buffer page size is now configurable and set to the proper PAGE_SIZE. Before, it was assumed to be always 4K. 2. Driver sometimes would crash when receiving jumbo packets mixed with firmware management packets. This was caused by the old firmware DMA'ing to the wrong address.

2008-05-02bnx2: Zero out context memory for 5709.Michael Chan

2008-05-02bnx2: Fix remote PHY initial link state.Michael Chan
On some remote PHY blade systems, the driver receives no initial link interrupt. As a result, the GMII/MII MAC mode does not get setup properly. To fix this problem, we add an initial poll of the link state after chip reset. With this change, the setting of the initial carrier state in the init code can be eliminated.

2008-05-02bnx2: Refine remote PHY locking.Michael Chan

We were checking for the ASYM_PAUSE bit for 1000Base-X twice instead checking for both the 1000Base-X bit and the 10/100/1000Base-T bit.

2007-12-11[BNX2]: Fix RX packet rot.Michael Chan
Packets can be left in the RX ring if the NAPI budget is reached. This is caused by storing the latest rx index at the beginning of bnx2_rx_int(). We may not process all the work up to this index if the budget is reached and so some packets in the RX ring may rot when we later check for more work using this stored rx index. The fix is to not store this latest hw index and only store the processed rx index. We use a new function bnx2_get_hw_rx_cons() to fetch the latest hw rx index.
