This MIB counter is similar to the one of TCP -- CurrEstab -- available in /proc/net/snmp. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. Patch 1 prepares its support by adding new helper functions: - MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to decrement a counter. - mptcp_set_state(): similar to tcp_set_state(), to change the state of an MPTCP socket, and to inc/decrement the new counter when needed. Patch 2 uses mptcp_set_state() instead of directly calling inet_sk_state_store() to change the state of MPTCP sockets. Patch 3 and 4 validate the new feature in MPTCP "join" and "diag" selftests.
