Subject: [PATCH net-next 2/8] selftests: mptcp: add testcases for setting the address ID

From: Geliang Tang <geliangtang@...il.com>

Since the address ID can be set from user-space, some of the tests in
pm_netlink.sh will fail. This patch fixed the failures, and add the
testcases for setting the address ID.
