Hmm, this means that a packet went through PRE_ROUTING, FORWARD and
POST_ROUTING, then hit loopback.

It's kinda wierd behaviour: multicast packets will pass through
PRE_ROUTING, FORWARD, POST_ROUTING (ip_mc_output), then net_rx,
net_rx_action, ip_rcv, then ???.

I'm surprised you don't get more messages, but they're fairly
harmless.
