mlxsw: Hardware monitoring enhancements
This patchset from Vadim provides various hardware monitoring related
improvements for mlxsw.
Patch #1 allows querying firmware version from the switch driver when
the underlying bus is I2C. This is useful for baseboard management
controller (BMC) systems that communicate with the ASIC over I2C.
Patch #2 improves driver's performance over I2C by utilizing larger
transactions sizes, if possible.
Patch #3 re-orders driver's initialization sequence to enforce a
specific firmware version before new firmware features are utilized.
This is a prerequisite for patches #4-#6.
Patches #4-#6 expose the temperature of inter-connect devices
(gearboxes) that are present in Mellanox SN3800 systems and split
2x50Gb/s lanes to 4x25Gb/s lanes.
Patches #7-#8 reduce the transaction size when reading SFP modules
temperatures, which is crucial when working over I2C.
