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

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!
