Merge branch 'mptcp-misc'
Mat Martineau says:
====================
MPTCP: Miscellaneous changes
Here is a collection of patches from the MPTCP tree:
Patches 1 and 2 add some helpful MIB counters for connection
information.
Patch 3 cleans up some unnecessary checks.
Patch 4 is a new feature, support for the MP_TCPRST option. This option
is used when resetting one subflow within a MPTCP connection, and
provides a reason code that the recipient can use when deciding how to
adapt to the lost subflow.
Patches 5-7 update the existing MPTCP selftests to improve timeout
handling and to share better information when tests fail.
