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

16 Contact: Xu Yilun <yilun.xu@intel.com>
17 Description: Read-only. Returns the enumeration value of the working mode of
18 the retimer A configured by the Nios firmware. The value is
19 read out from shared registers filled by the Nios firmware. Now
29 If the Nios firmware is updated in future to support more
30 retimer modes, more enumeration value is expected.

37 Description: Read-only. Returns the enumeration value of the working mode of
38 the retimer B configured by the Nios firmware. The value format
39 is the same as retimer_A_mode.
