2009-03-20ixgbe: Fixup the watchdog interrupt scheduling on 82599Jesse Brandeburg
The watchdog will schedule an interrupt to help make sure queues are cleaned in the case when an interrupt is missed, most likely due to very high load. On 82599, there are extra interrupt registers to account for the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for 82598).

2009-02-21ixgbe: fix for 82598 Si errata causing buffer overflowDon Skidmore
The failure happens when an interrupt occurs and the driver is reading EICR. This read will cause a clear-by-read which leads to two TLP being inserted in the PCIe retry buffer leading to an overflow of the buffer and corruption of TLPs. The solution is different depending where the reading of EICR takes place. For ixgbe_msix_lsc() since we are in MSIX mode and know OCD is enabled a clear-by-write is done instead of the normal clear-by-read. For ixgbe_intr() 0xffffffff is written to EIMC before the read, masking the interrupts.

2009-01-26ixgbe: fix slow load times on 82598 nicsDon Skidmore
Load times for NICs that use i2c to communicate with the phy were taking ~4.5 sec per port. This fix first checks to see if the link is already up before calling get_link_capabilities, since if it is we don't need query the phy for link state.
