6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hariprasad Kelam <hkelam@xxxxxxxxxxx>
[ Upstream commit 6fc2164108462b913a1290fa2c44054c70b060ef ]
The corrected words register(FCFECX_VL0_CCW_LO)/Uncorrected words
register (FCFECX_VL0_NCCW_LO) of FCFEC counter has different LMAC
offset which needs to be accessed differently.
Fixes: 84ad3642115d ("octeontx2-af: Add FEC stats for RPM/RPM_USX block")
