From 42842a425ad6d1ef1087b63486879a6d54b26893 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Wed, 9 Dec 2020 15:51:26 -0800 Subject: mptcp: drop rm_addr_signal flag This patch reused add_addr_signal for the RM_ADDR announcing signal, by defining a new ADD_ADDR status named MPTCP_RM_ADDR_SIGNAL. Then the flag rm_addr_signal in PM could be dropped. Signed-off-by: Geliang Tang Signed-off-by: Mat Martineau Signed-off-by: David S.
