rps: immediate send IPI in process_backlog()
If some skb are queued to our backlog, we are delaying IPI sending at the end of net_rx_action(), increasing latencies. This defeats the queueing, since we want to quickly dispatch packets to the pool of worker cpus, then eventually deeply process our packets. It's better to send IPI before processing our packets in upper layers, from process_backlog(). Change the _and_disable_irq suffix to _and_enable_irq(), since we enable local irq in net_rps_action(), sorry for the confusion. Signed-off-by:Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by:
