A few tests check if nettest exists in the $PATH before adding $PWD to $PATH and re-checking. They don't discard stderr on the first check (and nettest is built as part of selftests, so it's pretty normal for it to not be available in system $PATH). This leads to output noise:
which: no nettest in (/home/virtme/tools/fs/bin:/home/virtme/tools/fs/sbin:/home/virtme/tools/fs/usr/bin:/home/virtme/tools/fs/usr/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)
Add a common helper for the check which does silence stderr.
There is another small functional change hiding here, because pmtu.sh and fib_rule_tests.sh used to return from the test case rather than completely exit. Building nettest is not hard, there should be no need to maintain the ability to selectively skip cases in its absence.

Ah, sorry, I added timestamping output as a local patch for NIPA.
Random example:
TAP version 13 1..1 # overriding timeout to 7200 # selftests: net: amt.sh # 13.15 [+13.15] TEST: amt discovery [ OK ] # 16.27 [+3.12] TEST: IPv4 amt multicast forwarding [ OK ] # 19.14 [+2.86] TEST: IPv6 amt multicast forwarding [ OK ] # 670.88 [+651.74] TEST: IPv4 amt traffic forwarding torture [ OK ] # 1203.28 [+532.40] TEST: IPv6 amt traffic forwarding torture [ OK ] ok 1 selftests: net: amt.sh
It's not great, makes the lines longer and misaligned. But it's helpful for debugging slow tests.

To be clear the profile=1 enables the timestamps from my local patch

TAP version 13 1..1 # overriding timeout to 7200 # selftests: net: amt.sh # 13.15 [+13.15] TEST: amt discovery [ OK ] # 16.27 [+3.12] TEST: IPv4 amt multicast forwarding [ OK ] # 19.14 [+2.86] TEST: IPv6 amt multicast forwarding [ OK ] # 670.88 [+651.74] TEST: IPv4 amt traffic forwarding torture [ OK ] # 1203.28 [+532.40] TEST: IPv6 amt traffic forwarding torture [ OK ] ok 1 selftests: net: amt.sh

I think it's a good feature, maybe you can put it in mainline :)
Thanks Hangbin

Like Hangbin I am also not sure what "profile=1" is about, but looks fine otherwise, so:
