====================
mptcp: Selftest enhancement and fixes

This is a collection of selftest updates from the MPTCP tree.

Patch 1 uses additional 'ss' command line parameters and 'nstat' to
improve output when certain MPTCP tests fail.

Patches 2 & 3 fix a copy/paste error and some output formatting.

Patch 4 makes sure tests still pass if certain connection-related
packets are retransmitted.
