[Click] CLICK WITH ETH1 DEVICE

Hi Gaurav,
To enable a gateway, run the gen_config_roonfet.pl with the --gateway
argument. Then to see if it worked, run "cat /click/srcr_gw/is_gateway"
which should print "true".
Right now, roofnet doesn't work with orinico cards (it doesn't set the
bitrate correctly), so it may work, but things will be slightly askew.
