Subject: selftests: mptcp: join: fix 'delete and re-add' test
From: Andrea Claudi <aclaudi@xxxxxxxxxx>
commit aaf2123a5cf46dbd97f84b6eee80269758064d93 upstream.
mptcp_join 'delete and re-add' test fails when using ip mptcp:
$ ./mptcp_join.sh -iI
<snip>
002 delete and re-add before delete[ ok ]
mptcp_info subflows=1 [ ok ]
Error: argument "ADDRESS" is wrong: invalid for non-zero id address
after delete[fail] got 2:2 subflows expected 1
This happens because endpoint delete includes an ip address while id is
not 0, contrary to what is indicated in the ip mptcp man page:
"When used with the delete id operation, an IFADDR is only included when
the ID is 0."
This fixes the issue using the $addr variable in pm_nl_del_endpoint()
only when id is 0.
