Do we have any dependency between the two prs? |

Yes, the values added here can take effect only after the sonic-swss PR (sonic-net/sonic-swss#2158) is merged. |

There was a problem hiding this comment.
The line side SI settings may depend upon the type of optics for some platforms. In that case, Xcvrd should read these values based upon the media (see Ref) and publish to gearbox syncd to program the line side on the gearbox. Can we discuss this scheme in the community?

@prgeor , this gearbox_config.json here is just to provide some initial value like setting tuning values for brcm ASIC in brcm config file. For the dynamic tuning support (based on xcvr type), an idea is to add the support in the future with some extension to the usage of media_settings.json.

What I did This change adds support for setting tx tap or tuning values on gearbox ports. It uses the SAI attributes such as SAI_PORT_SERDES_ATTR_TX_FIR_PRE1 to communicate with SAI-based gearbox drivers. For the values, they are provided in the format like "system_tx_fir_pre2": [1,1] for an interface from gearbox_config.json. Why I did it How I verified it We verified that values provided in sonic-net/sonic-buildimage#10084 are set to the chip with this change. Added test to tests/test_gearbox.py. The added test will not pass until the following two changes (which should be merged first) are merged: Support SAI_PORT_ATTR_PORT_SERDES_ID on vs gearbox: sonic-net/sonic-sairedis#1082 Add gearbox taps to vs gearbox_config.json: sonic-net/sonic-buildimage#11480

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 I did it
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.
