2018-11-07tcp: consume incoming buffers instead of reusingFlorin Coras7-803/+727
Instead of reusing buffers for acking, consume all buffers and program output for (dup)ack generation. This implicitly fixes the drop counters that were artificially inflated by both data and feedback traffic. Moreover, the patch also significantly reduces the ack traffic as we now only generate an ack per frame, unless duplicate acks need to be sent. Because of the reduced feedback traffic, a sender's rx path and a receiver's tx path are now significantly less loaded. In particular, a sender can overwhelm a 40Gbps NIC and generate tx drop bursts for low rtts. Consequently, tx pacing is now enforced by default.

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.

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.
