octeontx2-pf: ethtool fec mode support
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 Signed-off-by: Christina Jacob <cjacob@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Reviewed-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: David S.
