Commit Message

Jacob Keller Aug. 15, 2023, 10:35 p.m. UTC 
The ice driver currently sets feature flags for certain PTP related
capabilities based on whether the device has support for the feature. Avoid
enabling these capabilities except on the ports which own the timer. This
ensures that the driver never attempts to access the features except on the
ports designated as controlling the main timer functionality.
