[PATCH mptcp-net v3] mptcp: netlink: process IPv6 addrs in creating listening sockets
Posted by Kishen Maloor 4 years ago 
This change updates mptcp_pm_nl_create_listen_socket() to create
listening sockets bound to IPv6 addresses (where IPv6 is supported).

Fixes: 1729cf186d8a ("mptcp: create the listening socket for new port")
