This adds iproute2 support for mptcp event monitoring, e.g. creation, establishment, address announcements from the peer, subflow establishment and so on. While the kernel-generated events are primarily aimed at mptcpd (e.g. for subflow management), this is also useful for debugging. This adds print support for the existing events. Sample output of 'ip mptcp monitor': [ CREATED] token=83f3a692 remid=0 locid=0 saddr4=10.0.1.2 daddr4=10.0.1.1 sport=58710 dport=10011 [ ESTABLISHED] token=83f3a692 remid=0 locid=0 saddr4=10.0.1.2 daddr4=10.0.1.1 sport=58710 dport=10011 [SF_ESTABLISHED] token=83f3a692 remid=0 locid=1 saddr4=10.0.2.2 daddr4=10.0.1.1 sport=40195 dport=10011 backup=0 [ CLOSED] token=83f3a692 Signed-off-by: Florian Westphal <fw@strlen.de>
