I only took the briefest of looks online, but from the very little I examined, I 
would surmise it is working at the data link layer.  So, it is then below all 
the routing "smarts" that intercepts local traffic and makes IP and above send 
to self more difficult.

FWIW, there are some ancient, and perhaps bit-rotten :) DLPI tests in netperf 
that were known to run on HP-UX and Solaris, and in theory one could add tests 
that used Linux's native link-layer access mechanism.

happy benchmarking,
