Subject: [PATCH net-next v3 0/3] NSH and VxLAN-GPE

These patches add a new module to support encap/decap of Network
Service Header (NSH) as defined in:

https://tools.ietf.org/html/draft-ietf-sfc-nsh-01

Both NSH Type 1 and Type 2 metadata are supported with a simple registration
hook to allow listeners to register to see packets with Type 1 or a specific
class of Type 2 metadata. NSH could be added to packets sent over a variety
of link types, eg. VxLAN, GRE, ethernet.

v2 - fix copyright notices and tidy up use of types

v3 - fix various style issues in nsh module
     remove VxLAN-GPE changes
     add nsh logging module as example
     add nsh netfilter encap target as example

The previous version included mods to allow NSH over VxLAN-GPE but I've
withdrawn this as VxLAN-GPE is currently being added in a much more complete
patchset. My intention would be to add NSH support on top of that once it's
applied.

I've added the NSH logging module to illustrate the use of the simple
mechanism to register for incoming decap'd NSH metadata.

I've added the NSH netfilter target to illustrate metadata being NSH
encap'd.
