From 9031d5f491b95710a1cf871818c7c9730ec50a1b Mon Sep 17 00:00:00 2001 From: Larysa Zaremba Date: Tue, 5 Dec 2023 22:08:34 +0100 Subject: ice: Support HW timestamp hint Use previously refactored code and create a function that allows XDP code to read HW timestamp. Also, introduce packet context, where hints-related data will be stored. ice_xdp_buff contains only a pointer to this structure, to avoid copying it in ZC mode later in the series. HW timestamp is the first supported hint in the driver, so also add xdp_metadata_ops.
