mlxsw: spectrum: Add Spectrum-2 ASIC port type-speed operations
Add Spectrum-2 ASIC port type-speed operations.
Since multiple ethtool link modes are represented using a single bit in the
ASIC, the driver forces the user to configure all types per a specific
speed. For example, if the user wants to advertise 100Gbps 4-lanes speed,
he should advertise all the types of 100Gbps 4-lanes speed that are
supported by the ASIC as shown below:
Supported ethtool bits for 100Gbps 4-lanes:
0x1000000000 100000baseKR4 Full
0x2000000000 100000baseSR4 Full
0x4000000000 100000baseCR4 Full
0x8000000000 100000baseLR4_ER4 Full
Command for advertising 100Gbps 4-lanes:
ethtool -s enp3s0np1 advertise 0xF000000000
