I still don't think it is appropriate for the UAPI to be defined in
terms of lanes. I would prefer to see it defined in terms of signal
modulation (for which multiple could conceivably exist for a given
lane configuration, even though no such ambiguity exists for today's
defined modes). Better stil

Some speeds can be achieved with different number of lanes. For example,
100Gbps can be achieved using two lanes of 50Gbps or four lanes of
25Gbps. This patch set adds a new selector that allows ethtool to
advertise link modes according to their number of lanes and also forc
