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.

I intentionally didn't change the error message "not an ethernet device". For
the purposes of pktgen, loopback devices act like ethernet devices.
