Subject: selftests: mptcp: join: use 'iptables-legacy' if available
From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx>
commit 0c4cd3f86a40028845ad6f8af5b37165666404cd upstream.
IPTables commands using 'iptables-nft' fail on old kernels, at least
5.15 because it doesn't see the default IPTables chains:
$ iptables -L
iptables/1.8.2 Failed to initialize nft: Protocol not supported
As a first step before switching to NFTables, we can use iptables-legacy
if available.
