Actually, "ethtool" is the desired tool for this job.
mii-diag only works for a subset of ethernet hardware, the hardware that
supports MII interface properly. Further, the SIOCxMIIxxx interface
does not support all the NIC diagnostic and tuning one would like to
do. That's why ethtool interface was created.
Now, with that said, it should be noted that like mii-diag, not all
drivers yet support this interface.
