[LARTC] Bypassing Loopback

[Larry Stilwell]

Is it possible to setup a route that will place the packet 'on the wire'
even if the destination is a local IP?  I have been through the iproute2
docs and nothing jumps out at me. I am working on a project measuring
network latency/jitter/etc and am currently using a GRE tunnel as the test
path for measuring the first leg.  The router at the other end of the tunnel
faithfully routes the packet back.  The problem stems from the fact that the
implementation is Java and 'raw socket' support is not available.
