All devices I have can handle ARP, so there was no need for such a
feature in the driver..
Last version of the driver also supports MBIM devices, which have no
MAC address at all
since payload is a pure IP, While considering changes this shall be
taken into account.
There is no way to find out if ARP is supported or not by looking at
CDC Ethernet
Networking or NCM Functional Descriptors. If control that flag to be
added to the driver,
it shall be based on matching VID/PID.

Alexey
