Patch 1 adds these counters: last_data_sent, last_data_recv and last_ack_recv. They are available in the MPTCP Info, so exposed via getsockopt(MPTCP_INFO) and the Netlink Diag interface. Patch 2 adds a test in diag.sh MPTCP selftest, to check that the counters have moved by at least 250ms, after having waited twice that time.
