Subject: [PATCH net-next 3/6] selftests: mptcp: move stats info in case of
errors to lib.sh
A few MPTCP selftests are using the same code to print stats in case of
error. This code can then be moved to mptcp_lib.sh.
No behaviour changes intended, except to print the error in red and to
stderr, like most error messages.
