[Intel-wired-lan] [PATCH net-next] ice: Add EXTTS feature to the feature bitmap

[Intel-wired-lan] [PATCH net-next] ice: Add EXTTS feature to the feature bitmap

[Anatolii Gerasymenko]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

External time stamp sources are supported only on certain devices. Enforce
the right support matrix by adding the ICE_F_PTP_EXTTS bit to the feature
bitmap set.
