Subject: [PATCH v8 4/4] mptcp: remove MPTCP_ADD_ADDR_IPV6 and MPTCP_ADD_ADDR_PORT
Date: Thu,  8 Jul 2021 01:01:41 +0800	[thread overview]
Message-ID: <1625677301-139357-5-git-send-email-liyonglong@chinatelecom.cn> (raw)
In-Reply-To: <1625677301-139357-1-git-send-email-liyonglong@chinatelecom.cn>

MPTCP_ADD_ADDR_PORT and MPTCP_ADD_ADDR_PORT are not necessary, we
can get these info from pm.local or pm.remote
