portable, PCMCIA and mii

Hi,

My PCMICA card does not seem to support mii-diag or ethtool.

The distribution is redhat FC3 and my card is an ne2000
compatible PCMCIA card. (dmesg). The module that controls
this card is pcnet_cs.

The card seems to work properly in all aspects, though
mii-diag and ethtool doesnt seem to work on it.

strace shows that MIIPHY ioctl fails on the interface with
not supported error.

Why is this so ? Do PCMCIA cards require some other ioctl
commands private to them for tools like mii to work ?

Thanks in Advance
Arun

The driver only knows how to access the MII for a subset of card
types. Unlike the basic NE2000 spec, there is no standard for how
to talk to the MII.
