This patch appears to be broken.
We have a dynamips / dynagen setup with 40 * Cisco 7200 routers. The core
router is configured to attach to our local real network using
In this configuration, with the patch, huge amounts of duplicate packets
are generated by dynamips flooding the local lan.
With the gen_eth.c patch removed, all is good again, except you can't ping
the dynamips routers from the host machine.
