[PATCH net-next 0/6] mptcp: Connection-time 'C' flag and two fixes

Here are six more patches from the MPTCP tree.

Most of them add support for the 'C' flag in the MPTCP connection-time
option headers. This flag affects how the initial address and port are
treated by each peer. Normally one peer may send MP_JOIN requests to the
remote address and port that were used when initiating the MPTCP
connection. The 'C' bit indicates that MP_JOINs should only be sent to
remote addresses that have been advertised with ADD_ADDR.

The other two patches are unrelated improvements.

Patches 1-4: Add the 'C' flag feature, a sysctl to optionally enable it,
and a selftest.

Patch 5: Adjust rp_filter settings in a selftest.

Patch 6: Improve rbuf cleanup for MPTCP sockets.
