…to DPDeinit state Description Credo AEC 400G needs to set low power mode when changing to DPDeinit state on firmware v4.1. After sonic-net#254 is merged, low power mode will not be set when changing to DPDeinit state. Motivation and Context This patch adds the code to set low power mode only when changing to DPDeinit state when the transceiver's vendor is 'Credo' and 'host_assign' is '1'(Which means the application mode only has 1 logical port on the transceiver). With this patch, the Credo AEC 400G can work correctly.

@CharlieChenEC I don't think we can keep add vendor specific checks in a code that is generic and expects all modules to follow CMIS spec

@CharlieChenEC please get the module updated to the firmware that is fully CMIS compliant. A module should honor low power mode at any time.

Credo AEC 400G firmware v4.1 needs to set low power mode when change to DPDeinit state
Description
Credo AEC 400G needs to set low power mode when changing to DPDeinit state on firmware v4.1. After #254 is merged, low power mode will not be set when changing to DPDeinit state.
Motivation and Context
This patch adds the code to set low power mode only when changing to DPDeinit state when the transceiver's vendor is 'Credo' and 'host_assign' is '1'(Which means the application mode only has 1 logical port on the transceiver). With this patch, the Credo AEC 400G can work correctly.
How Has This Been Tested?
Insert AEC 400G on AS9716 and verify the cable is link up.
