Caller of this function otx2_get_sset_count . Where driver suppose to return number of stats.
This function is just to update local netdev counters fec_corr_blks/ fec_uncorr_blks. So failure
Of this function should not effect.

Perhaps simpler to have a single exit from the critical section:
if (req)
otx2_update_lmac_fec_stats

Also, should this function return an error on failure? The caller
returns errors in other cases.

Add ethtool support to configure fec modes baser/rs and
support to fecth FEC stats from CGX as well PHY.
Configure fec mode
- ethtool --set-fec eth0 encoding rs/baser/off/auto
Query fec mode
- ethtool --show-fec eth0
