From 715c78a82e00f848f99ef76e6f6b89216ccba268 Mon Sep 17 00:00:00 2001 From: Matthieu Baerts matthieu.baerts@tessares.net Date: Sun, 28 May 2023 19:35:29 +0200 Subject: [PATCH] selftests: mptcp: join: skip if MPTCP is not supported

Selftests are supposed to run on any kernels, including the old ones not supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the test stops and is marked as "skipped".
