2010-08-19net: rps: skip fragment when computing rxhashChangli Gao
Fragmented IP packets may have no transfer header, so when computing rxhash, we should skip them. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-08-19ixgbe: rewrite ethtool test to use standard config functionsAlexander Duyck
This change makes it so that the ethtool loopback test uses the standard ring configuration and allocation functions.

2010-08-19ixgbe: update all DESC_ADV macros to accept a ring pointerAlexander Duyck
All of the DESC_ADV macros are currently needing the pointers to be de-referenced before accessing the ring.

2010-08-19ixgbe: move all GPIE register config into a single functionAlexander Duyck

2010-08-19ixgbe: remove redundant configuration of vmolr, rename generic variableAlexander Duyck
The vmolr is configured already in ixgbe_set_rx_mode for the PF so there is no need to set it again in ixgbe_configure_rx. Instead of using the variable name reg, it is easier to just rename it to gcr_ext to reflect the register contents that the variable holds.

2010-08-19ixgbe: consolidate all setting of MRQC into one functionAlexander Duyck
This change simplifies the configuration of MRQC by consolidating the setting of it into one function. As such the register is no longer set in multiple places which should make any future changes easier to work with. In addition we can combine RSS related register writes into the call since enabling all of those bits without enabling RSS itself in MRQC should have no effect.

2010-08-19ixgbe: combine two modifications of TXDCTL into oneAlexander Duyck

2010-08-19ixgbe: remove redundant DMA alignment codeAlexander Duyck
This patch removes the redundant DMA alignment code from the Rx buffer allocation path. This code is no longer necessary since all x86 buffers are now DMA aligned due to recent changes to NET_IP_ALIGN and NET_SKB_PAD. It also moves the setting of the Rx queue value into the allocation path since it is more likely that the queue mapping will still be in the cache at the time of allocation.
