It works as desired with --send-eth, but not with --send-ip. The commands used (carefully pasted) were nmap -e eth4 -S 172.29.86.4 --send-eth -Pn 69.160.42.66 and nmap -e eth4 -S 172.29.86.4 --send-ip -Pn 69.160.42.66 (Destination address is spammer IP) When the above lines have --route_dst and --iflist added the results look the same as before. I see in the patch that 'nmap' is making use of a Linux kernel routing facility when actually sending packets. With --send-ip traffic is sent out 'eth5' and is directed to the MAC of the 172.29.79.2 router address for that link.
That's good to hear. We are making progress. I've committed this patch that makes --send-eth work. I will look at why --send-ip does not choose the same route.
