I implemented something similar while allowing for virtual router like
applications.  I had to add a mark very early in the pkt rx logic in dev.c,
and had to add a 'skb_default_mark' member to the netdevice because
the route lookup is done before the normal iptables logic ran.  Without
this, if a flow already existed for pkts coming in eth1, if the packet came
back in eth2, it would use eth1's flow.

I'll dig out the patch if anyone is interested...
