The 16 bit cards are NE2000 clones.  Although PCMCIA has the capability
to operate at 8MB/sec transfer rate, most implementation operate as
slower than ISA speeds (5.33MB/sec).

The ASIX chip is basically a NE2000 design, with a faster serializer and
a MII transceiver.  You shouldn't expect much more than 10Mbps performance.

That shouldn't happen.  Check that the link partner isn't set to
forced-full-duplex mode.

Nope.  The Tulip driver supports the 88140 ASIX chip, which is a
32 bit chip with a completely different design.

For years the PCMCIA-cs system was the standard.  When the functionality
was gradually moved into the kernel, the interface changed repeatedly.
