10.6.2.1 Set Link Error Codes
The following rules are used to define the error code returned for Set Link command in case an invalid
configuration is requested:
1. Host Driver Check: If host device driver is present, return a Command Specific Response (0x9) with
a Set Link Host OS/Driver Conflict Reason (0x1).
2. Speed Present Check: If no speed is selected, return a General Reason Code for a failed command
(0x1) with Parameter Is Invalid, Unsupported, or Out-of-Range Reason (0x2).
3. Parameter Validity:
a. Auto Negotiation Parameter Validation: If Auto Negotiation is requested and none of the selected
parameters are valid for the device, return a General Reason Code for a failed command (0x1)
with a Parameter Is Invalid, Unsupported, or Out-of-Range Reason (0x2).
Note: This means that, for example, a command requesting 10G on a 1G device will succeed
provided that the command requests at least one other supported speed. The same goes for
an unsupported duplex setting (a device with no HD support will accept a command with both
FD and HD set), and also for HD being requested with speeds of 1G and higher as long as a
speed below 1G is also requested (and is supported in HD). The device will simply ignore the
unsupported parameters.
b. Force Mode Parameter Validation:
1. If more than one link speed is being forced, then return a a General Reason Code for a failed
command (0x1) and a Command Specific Reason with a Set Link Speed Conflict Error
(0x0905).
2. If more than one duplex setting is being forced, then return a General Reason Code for a
failed command (0x1) with Parameter Is Invalid, Unsupported, or Out-of-Range Reason
(0x2).
3. If 1G and above is requested with HD, then return a a General Reason Code for a failed
command (0x1) and a Command Specific Reason with Set Link Parameter Conflict Error
(0x0903).
4. Media Type Compatibility Check: If current media type is not compatible for the requested link
parameters, return a a General Reason Code for a failed command (0x1) and a Command Specific
Reason with Set Link Media Conflict Error (0x0902).
