Add the VNET_FEATURE_ARC_ORDER macro, which allows specification of
bulk order constraints. Here's an example:
VNET_FEATURE_ARC_ORDER(ip4_unicast_arc_order, static) = {
.arc_name = "ip4-unicast",
.node_names = VNET_FEATURES ("ip4-flow-classify",
"ip4-inacl",
"ip4-source-check-via-rx",
"ip4-source-check-via-any",
"ip4-source-and-port-range-check-rx",
"ip4-policer-classify",
"ipsec4-input",
"vpath-input-ip4",
"ip4-vxlan-bypass",
"ip4-not-enabled",
"ip4-lookup"),
};
Simply list feature nodes in the desired order, and you're
done. Multiple macro instances per are are fine / expected /
tested.
Under the covers: generate "a before b" tuples by chain-dragging
across the ordered list. No need to touch existing per-feature
constraints.
Fixed a long-broken "you lose!" error message.

There are two reasons to modify the existing code ip4_input_inline.
1. For many tunnel decap cases, inner ip header or its part is possible
in the second cacheline, not first cacheline only after the field "data",
and this will cause data cache miss once the second cacheline is needed
to access. e.g vxlan-gpe.
2. For most of cases, "data" is the starting address of ethernet
header, not IP header. The existing code causes misunderstanding
from code readability perspective.

Typically we have scalar_size == 0, so it doesn't matter
but vlib_frame_args was providing pointer to scalar frame
data, not vector data. To avoid future confusion function
is renamed to vlib_frame_scalar_args(...)

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.

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.
