The crash is because we access the null pointer rxvq->avail,
which is supposed to be derived from the mmap informed by the driver.
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.

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.

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.

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.

length in ip4 header could be 0, when the length edit is fixed
this happens if length is not specified or size is specified as, f.g., 100-100
As a result, tcp and icmp would get a negative value for checksum calculation

stream->max_packet_bytes
This length is the payload length, and will impact the ip length
when ip length is not specified. iplen = header_len + payload_len
SO, better to make it comply with max_packet_bytes

Fixed consistancy between the first classifier match and the
next_table_index classifier matches:
- CLASSIFY_ACTION_SET_METADATA was applied only for the first
classifier, but it was not applied for the other classifiers
- Actions should be performed only for input ACLs
- Payload should point at the IP header for output ACLs

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.

According to the RFC 4096 (section 3.3.1) the DATA chunk needs to be
padded to a boundary of 4 bytes with zeros. This patch addresses that
requirement.
At the same time, this patch takes care of adding some hardening for
corner-cases where the transmitted tag could be wrong.

Patch is too large to be ported to 18.10 just days before release.
- handle fast retransmits outside of established node and limit the
retransmit burst size to avoid tx losses and worsening congestion.
- in the absance of a tx pacer, use slow start after fast retransmit
exists
- add fast retransmit heuristic that re-retries sending the first
segment if everything else fails
- fine tuning
