Subject: [PATCH net-next 09/11] selftests: mptcp: add invert argument for chk_rm_nr

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

Some of the removing testcases used two zeros as arguments for chk_rm_nr
like this: chk_rm_nr 0 0. This doesn't mean that no RM_ADDR has been sent.
It only means that RM_ADDR had been sent in the opposite direction that
chk_rm_nr is checking.

This patch added a new argument invert for chk_rm_nr to allow it can
check the RM_ADDR from the opposite direction.
