From d5b6f6d595b446c1693fdaa6aeb4a65b94d5fc90 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 20 Dec 2023 13:41:39 +0200 Subject: wifi: mac80211: rework RX timestamp flags We only have a single flag free, and before using that for another mactime flag, instead refactor the mactime flags to use a 2-bit field.
