From: Matthieu Baerts (NGI0) Date: Mon, 10 Nov 2025 18:23:40 +0000 (+0100) Subject: selftests: mptcp: connect: fix fallback note due to OoO X-Git-Tag: v6.18-rc6~31^2~5^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=63c643aa7b7287fdbb0167063785f89ece3f000f;p=thirdparty%2Flinux.git selftests: mptcp: connect: fix fallback note due to OoO The "fallback due to TCP OoO" was never printed because the stat_ooo_now variable was checked twice: once in the parent if-statement, and one in the child one. The second condition was then always true then, and the 'else' branch was never taken. The idea is that when there are more ACK + MP_CAPABLE than expected, the test either fails if there was no out of order packets, or a notice is printed.
