Subject: [MPTCP] [PATCH net-next 04/11] mptcp: use adding up size to get ADD_ADDR length
Date: Wed, 09 Dec 2020 15:51:21 -0800	[thread overview]
Message-ID: <20201209235128.175473-5-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: 20201209235128.175473-1-mathew.j.martineau@linux.intel.com

From: Geliang Tang <geliangtang(a)gmail.com>

This patch uses adding up size to get the ADD_ADDR suboption length rather
than returning the ADD_ADDR size constants.
