I think it can, but it looks like it needs a different
implementation. The CDC NCM standard is publicly available. It
documents an optional call to set the MAC address, and there appears
to be a capability bit to indicate if its implemented in a specific
device. Ideally if the bit is not set -EOPNOTSUPP should be returned
when trying to set the MAC address, otherwise make the call to let the
hardware know of the new MAC address.

Sorry, i don't have the time or the hardware to actually implement
this. But i can review patches and help with processes.

Andrew
