Message-ID: <1285689517.3154.76.camel@edumazet-laptop>

Subject: [PATCH net-next2.6] net: rename netdev rx_queue to ingress_queue
There is some confusion with rx_queue name after RPS, and net drivers
private rx_queue fields.
I suggest to rename "struct net_device"->rx_queue to ingress_queue.
Signed-off-by: Eric Dumazet <eric.dumazet@...il.com>

My plan is to make this structure dynamically allocated, in the rare
case ingress is setup, to shrink net_device.
