[PATCH mptcp-next 0/6] Fix socket options used by NVMe over MPTCP

From: Geliang Tang <[email protected]>

NVMe over MPTCP relies on SO_LINGER, SO_PRIORITY, SO_REUSEADDR, TCP_SYNCNT,
TCP_NODELAY, IP_TOS, and SO_BINDTODEVICE. This series contains fixes to make
all of them work correctly. Patch 4 is a cleanup needed by patch 5. Patch 6
adds a selftest to cover these options.

Geliang Tang (6):
  mptcp: copy the subflow's rcv_tos to the msk on accept
  mptcp: don't reset dst when setting default 0 tos
  mptcp: inherit sk_reuse on subflow creation
  mptcp: handle TCP_MAXSEG getsockopt in common case
  mptcp: add TCP_SYNCNT setsockopt/getsockopt
  selftests: mptcp: sockopt: cover LINGER REUSEADDR PRIORITY NODELAY
    SYNCNT
