From 1e75629cb964b5b2fdf79553da8d1a3c72b62faa Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Fri, 4 Mar 2022 11:36:27 -0800 Subject: mptcp: add the mibs for MP_FASTCLOSE This patch added two more mibs for MP_FASTCLOSE, MPTCP_MIB_MPFASTCLOSETX for the MP_FASTCLOSE sending and MPTCP_MIB_MPFASTCLOSERX for receiving. Also added a debug log for MP_FASTCLOSE receiving, printed out the recv_key of MP_FASTCLOSE in mptcp_parse_option to show that MP_RST is received.
