Do we really want to reply to all the garbage tcpdump causes us to capture? That is what the pkt_type is dealing with. If we're in promiscuous mode, we'll hear ARP requests meant not for any of our devices, we should not proxy for them right? RTCF_*NAT is dead wood, the existing route nating stuff is totally broken an unusable in 2.6.x, the eventual plan was to code up XFRM engine version of that feature but this is of course not done. Since nobody is complaining about lack of routing NAT in 2.6.x, I think we should just kill off all references and if someone gets inspired they can code up the XFRM engine version.
