Can't make much of that though and googling hasn't helped so far.
The kernel internals are grumpy. I wouldn't worry about it, but google tells me it's to do with loading modules. So insmod or modprobe tg3 isn't enough; do lsmod |grep tg3, and try ifconfig eth0 followed by lsmod |grep tg3
Also, let's do this the proper way.
copy your Ethernet card line. Note the bus number at the beginning.
copy the same bus number. Then you can google that id in the form nnnn:nnnn
