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.

|
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.
