I didn't know this PR, but I found PR kern/13653 which also describes
a problem with the 3c905b. The problem (link goes away when interface
goes 'up' and won't come back) happens for me with a 3c905b PCI NIC,
not integrated onto the motherboard, and the suggested fix works for me.
I could not test with 100baseT yet, but with my old 10BaseT hub I did
_not_ have to specify the media with 'ifconfig', just the change in
if_ex_pci.c was sufficient.
