In the T2080 Ref Manual, Rev 4, 04/2021 the PROTS field (bits 20:24) in SerDesx_LNnGCR0 in section 19.4.18 is defined for some options but not all. We have SRDS_PRTCL_S1 in the RCW set to 0x66, so lane 3 (D) is configured for XFI. The SerDes1_LN3GCR0[PROTS] field is reporting 01010 which isn't defined in the Reference Manual. But the reference manual doesn't define what XFI should report in the PROTS field. Please let us know what the value should be when the lane is configured for XFI.
The value "01010'' for SerDes1_LN3GCR0[PROTS] is correct for XFI 10GBase-KR
