Merge branch 'mptcp-add-tcp_maxseg-sockopt-support'
Matthieu Baerts says:
====================
mptcp: add TCP_MAXSEG sockopt support
The TCP_MAXSEG socket option was not supported by MPTCP, mainly because
it has never been requested before. But there are still valid use-cases,
e.g. with HAProxy.
- Patch 1 is a small cleanup patch in the MPTCP sockopt file.
- Patch 2 expose some code from TCP, to avoid duplicating it in MPTCP.
- Patch 3 adds TCP_MAXSEG sockopt support in MPTCP.
- Patch 4 is not related to the others, it fixes a typo in a comment.
Note that the new TCP_MAXSEG sockopt support has been validated by a new
packetdrill script on the MPTCP CI:
