[net-next,0/7] mptcp: Add timestamp support

Enable the SO_TIMESTAMP and SO_TIMESTAMPING socket options for MPTCP
sockets and add receive path cmsg support for timestamps.

Patches 1, 2, and 5 expose existing sock and tcp helpers for timestamps
(no new EXPORT_SYMBOLS()s).

Patch 3 propagates timestamp options to subflows.

Patch 4 cleans up MPTCP handling of SOL_SOCKET options.

Patch 6 adds timestamp csmg data when receiving on sockets that have
been configured for timestamps.

Patch 7 adds self test coverage for timestamps.

  mptcp: setsockopt: handle SOL_SOCKET in one place only
  tcp: export timestamp helpers for mptcp
  mptcp: receive path cmsg support
  selftests: mptcp_connect: add SO_TIMESTAMPNS cmsg support
