[dpdk-dev] [PATCH v2 0/2] examples/l2fwd: Add option to enable/disable MAC addresses updating

[Maxime Coquelin <maxime.coquelin@redhat.com>]

This series adds a new option to enable/disable MAC addresses updating in
l2fwd example.

Doing that, we can enable basic VM 2 VM communication easily, without
external projects dependencies, nor real NIC (as with vhost example).

Example of cli with vhost-user:

#l2fwd -c f --socket-mem=1024 \
	--vdev 'eth_vhost0,iface=/tmp/vhost-user1,queues=1' \
	--vdev 'eth_vhost1,iface=/tmp/vhost-user2,queues=1' \
	-- -p3 --no-mac-updating

By default, MAC addresses updating remains enabled, but maybe we could
consider having it disabled by default to be consistent with l2fwd-cat
for example.

Changes since v1:
-----------------
 - Rebased on top of master branch
 - s/tweaking/updating/g (John)
 - Re-organize text around images
 - Apply John's Ack
