Subject: Allow pktgen to work with loopback devices.
From: Josh Triplett <josh@xxxxxxxxxxxxxxx>
pktgen currently only works on network devices with type ARPHRD_ETHER. Add
support for the loopback device, type ARPHRD_LOOPBACK.
I've tested this on my system, using a modified pktgen.conf-1-1 with
s/eth1/lo/g, and it works fine; the network device statistics confirm
packet transmission and receipt.
Thanks to Sarah Bailey for discovering and tracking down the problem.
