We fixed a similar issue before in https://gerrit.fd.io/r/#/c/14545/ The reason was the driver ummaps the memory without doing the disconnect in SR-IOV environment. The fixed was applied to the RX path. Now it happens in the TX path. We just need to apply the same check in the TX path.

2018-11-06tcp: dequeue acked only once per burstFlorin Coras4-28/+64
Avoid dequeuing acked bytes more than once per burst for a connection. Although the fifos do not use locks, size decrements are atomic, so they rely on locked instructions. Change-Id: Id65f4ea40b2c10057461402dfd0393034e6472d5 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-11-05vxlan: prefetch extra one cacheline holding external headerZhiyong Yang1-2/+2
For vxlan_encap, code will touch memory area before the field "data" in struct vlib_buffer_t, however so far it is not prefetched in cache yet for this graph node. After applying the patch, 2~3 cycles per pkt for vxlan4_encap can be saved on Haswell. It will bring a lot of benefits on DVN platform too.

2018-11-05Enable atomic swap and store macro with acquire and release orderingSirshak Das2-5/+9
Add atomic swap and store macro with acquire and release ordering respectively. Variable in question is interupt_pending variable which is used as guard variable by input nodes to process the device queue. Atomic Swap is used with Acquire ordering as writes or reads following this in program order should not be reordered before the swap. Atomic Store is used with Release ordering, as post store the node is added to pending list.

2018-10-25tcp/session: add tx pacerFlorin Coras10-21/+305
Adds tx pacing infrastructure for transport protocols that want to use it. Particularly useful for connections with non-negligible rtt and constrained network throughput as it avoids large tx bursts that lead to local interface tx or network drops. By default the pacer is disabled. To enabled it for tcp, add tx-pacing to tcp's startup conf. We are still slightly inefficient in the handling of incoming packets in established state so the pacer slightly affect maximum throughput in low lacency scenarios.

At the same time, this patch takes care of adding some hardening for corner-cases where the transmitted tag could be wrong.
