Decided to do some research and get this thing implemented right!
I've created a new patch against the 2.6.3-bk3 version of pcnet32.c
What this patch does is that in the event that mii is not supported,
link status is read directly from device's lnktst bcr register.
Works without any problem with the virtual nic under vmware. So if all
the other non-mii pcnet32 devices have the link status register in the
same place, things should be just fine!
Could you please test this and let me know what you think?
Best regards
Thomas
