Why I did it
This change specifies the tuning values for each lane of the B52 phy chips. These values can be different for different ports. The values being set are under the assumption of optical transceivers. This change depends on the change to sonic-swss: sonic-net/sonic-swss#2158.
How to verify it
We verified the values are correctly set on the B52 chips of Arista 7280cr3, by reading them from the debug cli of the B52 driver.
The v0.7.5 has bug fix for the support of gearbox port and macsec counters. It also includes a owl firmware update with owl.lz4.fw.1.94.0.bin.
How I did it
Update credo sai url for v0.7.5
Update gearbox_config.json with using firmware owl.lz4.fw.1.94.0.bin instead of owl.lz4.fw.1.92.1.bin
How to verify it
Test gearbox port and macsec counter successfully on A7280.
