Even if the 2nd > port is identified as port with pf_id = 1, all PHY operations need to be > performed as it was port 2. Thus, special mapping is needed for the 2nd port. > This change adds detection of 2x50G topology and applies 'custom' > mapping on the 2nd port. > > Signed-off-by: Grzegorz Nitka <[email protected]> > Reviewed-by: Arkadiusz Kubalewski <[email protected]> > Signed-off-by: Karol Kolacinski <[email protected]> > --- > V4 -> V5: - reworded commit mesage > - renamed GLGEN_SWITCH_MODE_CONFIG_SELECT_25X4_ON_SINGLE_QUAD_M to > GLGEN_SWITCH_MODE_CONFIG_25X4_QUAD_M > > .../net/ethernet/intel/ice/ice_hw_autogen.h | 4 ++++ > drivers/net/ethernet/intel/ice/ice_ptp.c | 5 +++++ > drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 22 +++++++++++++++++++ > drivers/net/ethernet/intel/ice/ice_type.h | 9 ++++++++ > 4 files changed, 40 insertions(+) >
