rndis_host: support Novatel Verizon USB730L 



Treat the ef/04/01 interface class/subclass/protocol combination used
by the Novatel Verizon USB730L (1410:9030) as a possible RNDIS
interface.

 T:  Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#= 17 Spd=480 MxCh= 0
 D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  3
 P:  Vendor=1410 ProdID=9030 Rev=03.10
 S:  Manufacturer=Novatel Wireless
 S:  Product=MiFi USB730L
 S:  SerialNumber=0123456789ABCDEF
 C:  #Ifs= 3 Cfg#= 1 Atr=80 MxPwr=500mA
 I:  If#= 0 Alt= 0 #EPs= 1 Cls=ef(misc ) Sub=04 Prot=01 Driver=rndis_host
 I:  If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=rndis_host
 I:  If#= 2 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=00 Driver=usbhid

Once the network interface is brought up, the user just needs to run a
DHCP client to get IP address and routing setup.

As a side note, other Novatel Verizon USB730L models with the same
vid:pid end up exposing a standard ECM interface which doesn't require
any other kernel update to make it work.
