Subject: [PATCH net-next 0/3] selftests: mptcp: add time per subtests in
 TAP output

Patches here add 'time=<N>ms' in the diagnostic data of the TAP output,
e.g.

  ok 1 - pm_netlink: defaults addr list # time=9ms

This addition is useful to quickly identify which subtests are taking a
longer time than the others, or more than expected.

Note that there are no specific formats to follow to show this time
according to the TAP 13, TAP 14 and KTAP specifications, but we follow
the format being parsed by NIPA [1].

Patch 1 modifies mptcp_lib.sh to add this support to all MPTCP
selftests.

Patch 2 removes the now duplicated info in mptcp_connect.sh

Patch 3 slightly improves the precision of the first subtests in all
MPTCP subtests.
