    mlxsw: core: Increase critical threshold for ASIC thermal zone · b06ca3d5

    Increase critical threshold for ASIC thermal zone from 110C to 140C
    according to the system hardware requirements. All the supported ASICs
    (Spectrum-1, Spectrum-2, Spectrum-3) could be still operational with ASIC
    temperature below 140C. With the old critical threshold value system
    can perform unjustified shutdown.
    
    All the systems equipped with the above ASICs implement thermal
    protection mechanism at firmware level and firmware could decide to
    perform system thermal shutdown in case the temperature is below 140C.
    So with the new threshold system will not meltdown, while thermal
    operating range will be aligned with hardware abilities.
