This patch series incorporates fixes and enhancements related to
path management over MPTCP connections, particularly in support of
userspace PMs. The changes ensure that the required bits of
information are conveyed through MPTCP netlink events which
would be consumed by the path manager in making its decisions.
Further it adds flexibility in establishing paths and from
both ends of MPTCP connections.

v6:
-Dropped framework and functionality around the use of kernel
listening sockets for receiving MPJs.

v7:
-Fixed bug caught by the CI build.

v8:
-Fixed logic to achieve the desired outcome of not responding to
address advertisements when a userspace PM is offline.
-Factored out minor changes to mptcp_pm_is_userspace() to be
squashed into an earlier commit.

Kishen Maloor (6):
  Squash-to: mptcp: Bypass kernel PM when userspace PM is enabled
  mptcp: bypass in-kernel PM restrictions for non-kernel PMs
  mptcp: store remote id from MP_JOIN SYN/ACK in local ctx
  mptcp: reflect remote port (not 0) in ANNOUNCED events
  mptcp: establish subflows from either end of connection
  mptcp: expose server_side attribute in MPTCP netlink events
