2009-04-27ixgbe: Fix WoL functionality for 82599 KX4 devicesWaskiewicz Jr, Peter P
The current code writes the PME enabled bit in PCI config space which is wrong. This was needed for pre-release hardware, and was not removed from the driver. Also, we need to clear the WUS (wake up status) after we resume. Otherwise we can't wake for the same event again since it's still asserted in the hardware. Plus, the multicast lists were being written improperly, causing multicast WoL to fail.

2009-04-17ixgbe: Fix DCB traffic class mapping for 82599PJ Waskiewicz
The traffic classes in hardware are not symmetrical for Rx and Tx. Rx is every 16 descriptor queues, Tx is not. It runs 32-32-16-16-8-8-8 when running with 8 traffic classes, and runs 64-32-16 when running with 4 traffic classes. This patch fixes the mapping.

2009-04-14ixgbe: fix tx queue indexWu Fengguang
Don't do the num_tx_queues based masking on calculating tx queue index. 1) num_tx_queues is not always power-of-2, because it also depends on the online cpu numbers. So the masking could be a performance bug on a 6 cpu system. 2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues in the generic netdev function set_cur_queue_map().

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). These must be taken into account when performing this operation in the watchdog.

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.

Register VLAN ID 0 so that frames with VLAN ID 0 are received and get their tag stripped when ixgbe is not in DCB mode. VLAN ID 0 means that the frame is 'priority tagged' only - it is not a VLAN, but the priority value is the tag in valid. The functions ixgbe_vlan_rx_register() and ixgbe_vlan_rx_kill_vid() were moved up a couple functions to correct compiling issues with this change.
