mlxsw: spectrum_ethtool: Add support for 100Gb/s per lane link modes

Browse source

The Spectrum-4 ASIC supports 100Gb/s per lane link modes, but the only
one currently supported by the driver is 800Gb/s over eight lanes.

Add support for 100Gb/s over one lane, 200Gb/s over two lanes and
400Gb/s over four lanes.
