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.
