From bab6b88e056038f618b2fb977d95b05ad3da8d0c Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Tue, 22 Jun 2021 12:25:19 -0700 Subject: mptcp: add allow_join_id0 in mptcp_out_options This patch defined a new flag MPTCP_CAP_DENY_JOIN_ID0 for the third bit, labeled "C" of the MP_CAPABLE option. Add a new flag allow_join_id0 in struct mptcp_out_options. If this flag is set, send out the MP_CAPABLE option with the flag MPTCP_CAP_DENY_JOIN_ID0.
