OK, so we're probably doing something wrong. I suspect we're not
alone.  At least we don't set SUPPORTED_TP for CX4, like I've
seen some NICs do.

Can somebody suggest how we can tell ethtool that
the NIC supports 10Gb only (no autoneg down to 1Gb or lower)
for copper (10Gbase-CX4)?   How about for fiber (10Gbase-{S,L})R?

Thanks,

Drew
