This patch significantly improves vhost Tx and Rx
performance (20% Mpps improvement in PVP scenario).
Most significant change consists in the split of
virtio ring parsing and memory copies.
Other minor changes mostly consist in getting
rid of unnecessary variables.

After a bug was found, I decided to review old vhost code.
This change cleans some of it by:
- Use unix file private data rather than hash table
- Use vnet interface lookups rather than hash table
- Keep track of unix_fd index rather than fd value
- Change some indent
- Store interfaces in a clib pool rather than hand-made pool
The overall change reduces the number of lines as well as
the amount of state kept in vhost structures.

Add a flag to the vnet_buffer to indicate a packet is locally originated. Then in the rewrite nodes we can check this flag and not perform the TTL decrement. The switch path cost is expected to be fractions of a clock - the flags will be hot in the cache.
The cehcks are necessary to due the requirements that VPP must be able to emit an IP packet with TTL=255.

Add ICMP echo reply punt logic in ip[46]-icmp-echo-reply (ping) nodes.
ICMP echo reply packets corresponding to the locally (VPP) originated
ICMP echo requests are still dropped as before. Rest of the (unknown)
ICMP echo reply packets are pushed to the “error-punt” node.
Also added ICMP echo packet (id/seq) trace information

These changes are incompatible with Python VPP API 1.2
There is now a new VPP Class and it can be used like:
from vpp_papi import VPP
jsonfiles = []
for root, dirnames, filenames in os.walk('../../../build-root/'):
if root.find('install-') == -1: continue
for filename in fnmatch.filter(filenames, '*.api.json'):
jsonfiles.append(os.path.join(root, filename))
vpp = VPP(jsonfiles)
rv = vpp.show_version()
print('RV', rv.program.decode().rstrip('\0x00'))
vpp.disconnect()

This patch should dispose of spurious objections around interface tag
requirements, currently in use as excuses not to support the vpp ML2
plugin.
Add "u8 tag[64];" to the sw_interface_details message sent by vpp to
control-plane clients. Add u8 tag[64] to the create_vhost_user_if and
tap_connect APIs.
Added debug CLI to set/show/clear the interface tag on any vnet sw
interface. Added the sw_interface_tag_add_del API to set/clear
tags on any vnet sw interface.
There can be no expectation of "tag atomicity" with respect to
physical hardware. Vpp discovers devices before establishing a
control-plane connection.
This patch upload verifies using the csit oper-161128 branch

Added vxlan-bypass feature which can be enabled on the underlay
interface which receive VXLAN packets to accelerate VXLAN decap
processing. The CLI to enable it is:
set interface ip vxlan-bypass <interface> [del]
With this feature enabled on an interface, there is an overhead for
non-VXLAN packets at about 13 clocks per packet.
The API is created to support vxlan-bypass for both VXLANoIPv4 and
VXLANoIPv6. With this change, vxlan-bypass is only implemented for
IPv4 forwarding path.
