mptcp: create subflow or signal addr for newly added address

Browse source

Currently, when a new MPTCP endpoint is added, the existing MPTCP
sockets are not affected.

This patch implements a new function mptcp_nl_add_subflow_or_signal_addr,
invoked when an address is added from PM netlink. This function traverses
the MPTCP sockets list and invokes mptcp_pm_create_subflow_or_signal_addr
to try to create a subflow or signal an address for the newly added
address, if local constraint allows that.
