Subject: [PATCH net-next 2/7] selftests: mptcp: sockopt: use IPPROTO_MPTCP
for getaddrinfo
From: Geliang Tang <tanggeliang@...inos.cn>
getaddrinfo MPTCP is recently supported in glibc and IPPROTO_MPTCP for
getaddrinfo is used in mptcp_connect.c. But in mptcp_sockopt.c and
mptcp_inq.c, IPPROTO_TCP are still used for getaddrinfo, So this patch
updates them.
