**my opinion**
- Is it a problem with the mii module? Because mii is not loaded after igb is loaded
- Problems with the software itself (if there is no mii module)

**man page**

DIAGNOSTICS SIOCGMIIPHY on 'eth?' failed: Operation not supported The interface in question does not support MII queries. Most likely, it does not have MII transceivers, at all.


And It seem that NIC supported.

Is ethtool working or not? (I.e. is it communicating?), not sure from the output.

Can you also write two strace files of the two tools?

ethtool can work.I use ping.

ecki commented 3 years ago

Hm yeah looks like it only supports the SIOCETHTOOL but not the SIOCSMIIREG ioctl, that could be expected, I am not sure how the current strategy of driver makers is in this regard. mii-tool might be deprecated for a reason. We probably could add a fallback on ENOTSUPP - not sure how compatible the parameter logic is. Anybody tried this? (there is no change for this in 2.10 AFAIK).
