2010-05-10net: trans_start cleanupsEric Dumazet
Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-05-06bnx2: Add prefetches to rx path.Michael Chan
Add prefetches of the skb and the next rx descriptor to speed up rx path. Use prefetchw() for the skb [suggested by Eric Dumazet]. The rx descriptor is in skb->data which is mapped for streaming mode DMA. Eric Dumazet pointed out that we should not prefetch the data before dma_sync.

2010-05-06bonding: make bonding support netpollWANG Cong
Based on Andy's work, but I modified a lot. Similar to the patch for bridge, this patch does: 1) implement the 2 methods to support netpoll for bonding; 2) modify netpoll during forwarding packets via bonding; 3) disable netpoll support of bonding when a netpoll-unabled device is added to bonding; 4) enable netpoll support when all underlying devices support netpoll.

2010-05-06netpoll: add generic support for bridge and bonding devicesWANG Cong
This whole patchset is for adding netpoll support to bridge and bonding devices. I already tested it for bridge, bonding, bridge over bonding, and bonding over bridge. It looks fine now. To make bridge and bonding support netpoll, we need to adjust some netpoll generic code. This patch does the following things: 1) introduce two new priv_flags for struct net_device: IFF_IN_NETPOLL which identifies we are processing a netpoll; IFF_DISABLE_NETPOLL is used to disable netpoll support for a device at run-time; 2) introduce one new method for netdev_ops: ->ndo_netpoll_cleanup() is used to clean up netpoll when a device is removed. 3) introduce netpoll_poll_dev() which takes a struct net_device * parameter; export netpoll_send_skb() and netpoll_poll_dev() which will be used later; 4) hide a pointer to struct netpoll in struct netpoll_info, ditto. 5) introduce ->real_dev for struct netpoll. 6) introduce a new status NETDEV_BONDING_DESLAE, which is used to disable netconsole before releasing a slave, to avoid deadlocks.

2010-05-06ixgbevf: Cache PF ack bit in interruptGreg Rose
When the PF acks a message from the VF the VF gets an interrupt. It must cache the ack bit so that polling SW will not miss the ack. Also avoid reading the message buffer on acks because that also will clear the ack bit.

2010-05-06ixgbe: Streamline MC filter setup for VFsGreg Rose
The driver was calling the set Rx mode function for every multicast filter set by the VF. When starting many VMs where each might have multiple VLAN interfaces this would result in the function being called hundreds or even thousands of times. This is unnecessary for the case of the imperfect filters used in the MTA and has been streamlined to be more efficient.

2010-05-05e1000e: increase rx fifo size to 36K on 82574 and 82583Alexander Duyck
This change increases the RX fifo size to 36K for standard frames and decreases the TX fifo size to 4K. The reason for this change is that on slower systems the RX is much more likely to backfill and need space than the TX is. As long as the TX fifo is twice the size of the MTU we should have more than enough TX fifo.
