[PATCH iproute2-next v2] mptcp: add the fullmesh flag setting support

Posted by Geliang Tang 1 week, 6 days ago
This patch added the fullmesh flag setting support.

 ip mptcp endpoint change id 1 fullmesh
 ip mptcp endpoint change id 1 nofullmesh

Added the fullmesh flag check for the adding address too.

Needs to apply the patch "mptcp: add id check for deleting address"
first.

 v2:
 - drop MPTCP_PM_ADDR_FLAG_NOFULLMESH.
 - rename MPTCP_PM_ADDR_FLAG_NOBACKUP to MPTCP_PM_ADDR_FLAG_NONE.
