It took me over 30 minutes of testing to figure out what went wrong here.
The correct media type is '10baseT', not '10BaseT'.
Because the string didn't match exactly the 'mii-diag' program interpreted
the to-advertise value as the number "0x10ba" rather than the translated
0x0060.

Try '-A 10baseT'.  I will add code to avoid this in the future.
