Hi,

i suggest to implement a new action 'setnexthop' which stores the
next hop as an MTAG with the packet (so it is preserved if the
packet gets passed to dummynet).
I took a quick look at how ipfw forward has been implemented.
It seems to use PACKET_TAG_IPFORWARD to store routing info.
If I would implement "ipfw setnexthop" with a new MTAG it
would duplicate very much code already present for PACKET_TAG_IPFORWARD.
If I could reuse the same MTAG this would be easier to add, all
that would be needed is a new opcode for ipfw (or am I missing
something important ?)
