Here are a few fixes related to MPTCP:

- Patch 1 limits GSO max size to ~64K when MPTCP is being used due to a
  spec limit. 'gso_max_size' can exceed the max value supported by MPTCP
  since v5.19.

- Patch 2 fixes a possible NULL pointer dereference on close that can
  happen since v6.7-rc1.

- Patch 3 avoids sending a RM_ADDR when the corresponding address is no
  longer tracked locally. A regression for a fix backported to v5.19.

- Patch 4 adds a missing lock when changing the IP TOS with setsockopt().
  A fix for v5.17.

- Patch 5 fixes an expectation when running MPTCP Join selftest with the
  checksum option (-C). An issue present since v6.1.
