[Intel-wired-lan] [PATCH iwl-next 0/4] ice: refactor PTP feature flags

[Jacob Keller <jacob.e.keller@intel.com>]

This series refactors and extends the feature flag detection for a couple of
PTP feature flags. This includes ICE_F_GNSS and ICE_F_SMA_CTRL. Instead of
blindly assuming the feature is enabled on all E810-T devices, check the
netlist to confirm that the feature is supported on that device and
platform.

For SMA control, this allows the driver to fallback to the fixed pin
configuration that is supported by default E810 configurations when the SMA
control is not accessible.

For GNSS, this ensures that we do not attempt to read the GNSS portion of
the device if its not present, avoiding some unnecessary warning messages.

For ICE_F_SMA_CTRL this could be seen as a fix, but given the scope of the
code I decided that its next material. I think of it more as extending the
feature capability to support pins on more platforms.

Jacob Keller (4):
  ice: remove ICE_F_PTP_EXTTS feature flag
  ice: don't enable PTP related capabilities on non-owner PFs
  ice: check the netlist before enabling ICE_F_SMA_CTRL
  ice: check netlist before enabling ICE_F_GNSS
