As with the "cdc_subset" and "asix" drivers, this just moves the net1080
support into its one driver module.  In this case there's a small bit of
extra cleanup involved, moving some funky framing logic into the tx_fixup()
routine (resolving a long overdue FIXME).

Minor historical note:  "usbnet" started out as "net1080", then got
generalized to make it easier for other network drivers to reuse the
urb queueing and fault management code here.
