Subject: [PATCH net-next v3 07/11] selftests: kselftest_harness: print test name for SKIP

From: Jakub Kicinski <[email-masked]>
Date: Tue, 20 Feb 2024 11:22:31 -0800

Jakub points out that for parsers it's rather useful to always
have the test name on the result line. Currently if we SKIP
(or soon XFAIL or XPASS), we will print:

ok 17 # SKIP SCTP doesn't support IP_BIND_ADDRESS_NO_PORT

     ^
     no test name

Always print the test name.
KTAP format seems to allow or even call for it, per:
