Subject: [net-next, v5, 07/11] mptcp: setsockopt: convert to mptcp_setsockopt_sol_socket_timestamping()
Date: Wed, 30 Jun 2021 16:11:58 +0800	[thread overview]
Message-ID: <20210630081202.4423-8-yangbo.lu@nxp.com> (raw)
In-Reply-To: <20210630081202.4423-1-yangbo.lu@nxp.com>

Split timestamping handling into a new function
mptcp_setsockopt_sol_socket_timestamping().
This is preparation for extending SO_TIMESTAMPING
for PHC binding, since optval will no longer be
integer.
