The question is what does TP mean? I found out MII means media independent interface. Also I am wondering why can't I change the value of port:
# ethtool -s eth0 port tp
Cannot set new settings: Invalid argument
not setting port
I thought about this. But how could an integrated single port eth card have both - mii and TP? Or is it the case that the TP phy is connected through card's mii port and it is just not possible to select the other one? I assume the card has two ports but only one is wired for use in the device. – akostadinov – 2013-09-09T11:39:50.107
Never payed attention to that bit, to be honest. Hopefully someone else will have a better (complete) answer. – Ярослав Рахматуллин – 2013-09-09T13:29:37.203
