Additional whitelist PID to the wwan whitelist in cdc_ether

Hi Dave,
	I wonder if you might accept this patch to add an additional device to the 
wwan whitelist in the cdc_ether driver?

	In addition I wonder if the default interface flags are correct for wwan 
devices? I would have expected to have 'IFF_NOARP' and 'IFF_POINTTOPOINT' 
flags set, as this is essentially a ptp link that's not arp capable and 
broadcast makes no sense. In any case for me I always have to turn off arp 
with ifconfig to get any traffic through the device.


Best regards,


Andrew
