[PATCH] 2.6.3 pcnet32.c fix link reporting for non-mii devices

[Thomas Munck Steenholdt <tmus@tmus.dk>]

Hi Guys!

A lot of people have been experiencing problems with the pcnet32 nic 
driver that
always returns link down on some devices (including the VMware vlance 
adapter).

The patch makes sure that link is always reported as up (in contrast to 
always
being rported as down) if the device is not MII capable. Devices that 
ARE MII
capable will return whatever mii_link_ok() says.

Please let be know what you think and possible give me a hint as to how 
I can
make sure this fix gets included whereever such a patch should be included!

Thanks a lot!
