Subject: [PATCH net-next 00/10] mptcp: New features for MPTCP sockets and netlink PM

This collection of patches adds MPTCP socket support for a few socket
options, ioctls, and one ancillary data type (specifics for each are
listed below). There's also a patch modifying the netlink MPTCP path
manager API to allow setting the backup flag on a configured interface
using the endpoint ID instead of the full IP address.

Patches 1 & 2: TCP_INQ cmsg and selftests.

Patches 2 & 3: SIOCINQ, OUTQ, and OUTQNSD ioctls and selftests.

Patch 5: Change backup flag using endpoint ID.

Patches 6 & 7: IP_TOS socket option and selftests.

Patches 8-10: TCP_CORK and TCP_NODELAY socket options. Includes a tcp
change to expose __tcp_sock_set_cork() and __tcp_sock_set_nodelay() for
use by MPTCP.


Davide Caratti (1):
  mptcp: allow changing the "backup" bit by endpoint id

Florian Westphal (6):
  mptcp: add TCP_INQ cmsg support
  selftests: mptcp: add TCP_INQ support
  mptcp: add SIOCINQ, OUTQ and OUTQNSD ioctls
  selftests: mptcp: add inq test case
  mptcp: getsockopt: add support for IP_TOS
  selftests: mptcp: check IP_TOS in/out are the same

Maxim Galaganov (3):
  tcp: expose __tcp_sock_set_cork and __tcp_sock_set_nodelay
  mptcp: expose mptcp_check_and_set_pending
  mptcp: support TCP_CORK and TCP_NODELAY
