[c-nsp] Set a L3 routed interface on a 6500 + SUP2 to 'promiscuous'mode?

VACL Capture on OSM/SPA/LAN interfaces or even SPAN on LAN interfaces should
work fine.

What info does the server receive when it arps for a remote address. I'll
assume that both ends have a /30 configured, and you aren't attempting to
use Proxy-arp.
