We ack I-frames on each txWindow/5 I-frames received, but if the sender stop to send I-frames and it's not a txWindow multiple we can leave some frames unacked. So I added a timer to ack I-frames on this case. The timer expires in 200ms. Signed-off-by: NGustavo F.

It also fix a bug: we weren't acknowledging I-frames when P=1. Note that when F=1 we are acknowledging packets before setting RemoteBusy to False. The spec says we should do that in the opposite order, but acknowledment of packets doesn't care about RemoteBusy flag so we can do that in the order we want. Signed-off-by: NGustavo F.

A while back there was a discussion regarding the rt_secret_interval timer. Given that we've had the ability to do emergency route cache rebuilds for awhile now, based on a statistical analysis of the various hash chain lengths in the cache, the use of the flush timer is somewhat redundant. This patch removes the rt_secret_interval sysctl, allowing us to rely solely on the statistical analysis mechanism to determine the need for route cache flushes.

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. So we prefetch only if dma_sync is no_op on the system. Signed-off-by: NMichael Chan <mchan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
