2008-11-20netdev: add more functions to netdevice opsStephen Hemminger
This patch moves neigh_setup and hard_start_xmit into the network device ops structure. For bisection, fix all the previously converted drivers as well. Bonding driver took the biggest hit on this. Added a prefetch of the hard_start_xmit in the fast path to try and reduce any impact this would have. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2008-11-16ixgbe: Fix usage of netif_*_all_queues() with netif_carrier_{off|on}()PJ Waskiewicz
netif_carrier_off() is sufficient to stop Tx into the driver. Stopping the Tx queues is redundant and unnecessary. By the same token, netif_carrier_on() will be sufficient to re-enable Tx, so waking the queues is unnecessary.

2008-11-12netdevice: safe convert to netdev_priv() #part-1Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>

most of the time we only need 1500 bytes for a packet which means we don't need a whole 4k page for each packet.
