From 45bcc0346561daa3f59e19a753cc7f3e08e8dff1 Mon Sep 17 00:00:00 2001 From: Geliang Tang tanggeliang@kylinos.cn Date: Fri, 1 Mar 2024 18:11:22 +0100 Subject: [PATCH] selftests: mptcp: diag: return KSFT_FAIL not test_cnt
The test counter 'test_cnt' should not be returned in diag.sh, e.g. what if only the 4th test fail? Will do 'exit 4' which is 'exit ${KSFT_SKIP}', the whole test will be marked as skipped instead of 'failed'!
So we should do ret=${KSFT_FAIL} instead.
