From fdf0f60a2bb02ba581d9e71d583e69dd0714a521 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" matttbe@kernel.org Date: Tue, 15 Jul 2025 20:43:29 +0200 Subject: [PATCH] selftests: mptcp: connect: also cover checksum
The checksum mode has been added a while ago, but it is only validated when manually launching mptcp_connect.sh with "-C".
The different CIs were then not validating these MPTCP Connect tests with checksum enabled. To make sure they do, add a new test program executing mptcp_connect.sh with the checksum mode.
