[MPTCP] [PATCH v2 0/6] IPv6 support

[Peter Krystad <peter.krystad at linux.intel.com>]

Implemented support for IPv6. selftests pass with ipv6=true, but
they take twice as long to run...

With re-factoring the addition of IPv6 is very clean but I did not
split files yet as it will be hard to squash any changes after the
such a split.

Still to do: multiple subflows, handling IPv4-mapped connections.

v2: Added further re-factoring that makes IPv6 change even smaller
    Add mptcpv6_init() stub and verified build with IPv6=n and m

    Kconfig changes submitted in earlier patch set, this set depends
    on those changes being merged.

    Squashing the final patch (6/6) so that IPv6 support occurs before
    the kselftests commit will be complicated.

Peter Krystad (6):
  mptcp: Reference icsk_af_ops routines through saved pointer
  mptcp: Reference inet_stream_ops routines through socket->ops
  mptcp: Re-factor mptcp_getname routine to be af-agnostic
  mptcp: Re-factor subflow_v4_conn_request to be af-agnostic
  mptcp: Export low-level routines for IPv6
  mptcp: Add IPv6 support
