[ovs-dev] [PATCH v3 0/2] nsh: rework NSH netlink keys and actions

[Yi Yang]

v2->v3
  - Fix several comments Jan Scheurich

v1->v2
  - Rework per kernel datapath review comments
  - Add new NSH key ttl
  - Add many helpers in nsh.h and replace much code
    with these helpers
  - nsh.h includes the lasted NSH spec
  - bits of flags and mdtype have a change

This patch seires reworks NSH netlink keys and actions
per kernel datapath requirments. OVS_KEY_ATTR_NSH is
changed as a nested key, encap_nsh and decap_nsh are
renamed as push_nsh and pop_nsh. PUSH_NSH used nested
OVS_KEY_ATTR_NSH keys to transfer NSH header data.

It also adds new NSH key 'ttl' to follow the lasted
IETF NSH draft:

https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/

I have double confirmed from one of its authors, this
is a final version which will be approved as IETF RFC,
the NSH header format won't be change anymore.
