Subject: [net-next 0/7][pull request] ipv6: Extension header infrastructure 

This patchset improves the IPv6 extension header infrastructure
to make extension headers more usable and scalable.

  - Reorganize extension header files to separate out common
    API components
  - Create common TLV handler that will can be used in other use
    cases (e.g. segment routing TLVs, UDP options)
  - Allow registration of TLV handlers
  - Elaborate on the TLV tables to include more characteristics
  - Add a netlink interface to set TLV parameters (such as
    alignment requirements, authorization to send, etc.)
  - Enhance validation of TLVs being sent. Validation is strict
    (unless overridden by admin) following that sending clause
    of the robustness principle
  - Allow non-privileged users to set Hop-by-Hop and Destination
    Options if authorized by the admin

The following are changes since commit c76c992525245ec1c7b6738bf887c42099abab02:
  nexthops: remove redundant assignment to variable err
and are available in the git repository at:
