[RFC mptcp-next v3 0/8] MPTCP KTLS support

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

v3:
 - mptcp_read_sock() and mptcp_poll() are not exported, as mptcp_sockopt
   test does not use read_sock/poll interfaces. They will be exported when
   new tests are added in the future.
 - call mptcp_inq_hint in tls_device_rx_resync_new_rec(),
   tls_device_core_ctrl_rx_resync() and tls_read_flush_backlog() too.
 - update selftests. 

v2:
 - fix disconnect.
 - update selftests.

This series adds KTLS support for MPTCP. Since the ULP of msk is not being
used, ULP KTLS can be directly configured onto msk without affecting its
communication.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/480

Depends on: implement mptcp read_sock, v13
Based-on: <cover.1761198660.git.geliang@kernel.org>
