IETF draft at:
https://tools.ietf.org/html/draft-ietf-sfc-nsh-01
defines a new protocol named Network Service Header (NSH) for
Service Function Chaining. This patch implements the data plane
handling for the NSH header, e.g. pushing/popping NSH header,
parsing NSH header, etc.
To remove dependency for Simon Horman's patch at:
http://openvswitch.org/pipermail/dev/2016-June/072010.html
We derived some codes to add the push_eth/pop_eth flow actions
to enable Ethernet as the encapsulation layer.
