…ics with (sonic-net#20527) For 40G optics there is SAI handling of T0 facing ports to be set with SR4 type and unreliable los set for a fixed set of ports. For this property to be invoked the requirement is set phy_unlos_msft=1 in config.bcm. This change is to meet the requirement and once this property is set, the los/interface type settings is applied by SAI on the required ports. Signed-off-by: Vaibhav Dahiya <vdahiya@microsoft.com>

phy_unlos_msft=1 in config.bcm.
This change is to meet the requirement and once this property is set, the los/interface type settings is applied by SAI on the required ports.
Why I did it
can be achieved by turning on Unreliable LOS and SR4 media_type for all ports which are connected to T1/T0.
The property phy_unlos_msft=1 is to exclusively enable this property.
