 | |
| Description:	Read-only. Returns the FEC mode of the 25G links of the
 | |
| 		ethernet retimers configured by Nios firmware. "rs" for Reed
 | |
| 		Solomon FEC, "kr" for Fire Code FEC, "no" for NO FEC.
 | |
| 		"not supported" if the FEC mode setting is not supported, this
 | |
| 		happens when the Nios firmware version major < 3, or no link is
 | |
| 		configured to 25G.
 | |
| 		Format: string

 | |
| Description:	Read-only. Returns the enumeration value of the working mode of
 | |
| 		the retimer A configured by the Nios firmware. The value is
 | |
| 		read out from shared registers filled by the Nios firmware. Now
 | |
| 		the values could be:
 | |
| 
 | |
| 		- "0": Reset
 | |
| 		- "1": 4x10G
 | |
| 		- "2": 4x25G
 | |
| 		- "3": 2x25G
 | |
| 		- "4": 2x25G+2x10G
 | |
| 		- "5": 1x25G
 | |
| 
 | |
| 		If the Nios firmware is updated in future to support more
 | |
| 		retimer modes, more enumeration value is expected.
