-  Add private tx/rx buffer management to support large frame sizes and update
   the rx code to handle multiple frames in a single usb transfer.  AX772 parts
   (at least) exhibit many input errors when operated with a 2K rx buffer and
   no errors w/ a 4K rx buffer (it's unclear what the cause of the errors is
   for 2K so this may just be covering up the real issue).  Larger rx buffer
   sizes show no significant performance improvement for AX772.  Bypassing the
   common buffer management routines also eliminates an extra context switch on
   every packet which noticeably improves performance (TCP netperf rx goes from
   45 Mb/s to 85 MB/s).

-  Apply le*toh() or htole*() to the variables of which we use the address as
   the buffer pointer in the call to axe_cmd(). This is needed to make the code
   work on big-endian machines.

-  Add support for the Apple USB Ethernet adapter.  Work around the "latch in
   at the first working PHY address hack", that fails for this adapter because
   it returns 0xffff when reading from lower PHY addresses. Also add more
   debugging printfs
