From 9d2bb84d54a40361c7008b33a60dc24f78724746 Mon Sep 17 00:00:00 2001 From: Shaul Triebitz Date: Tue, 2 Aug 2022 15:22:42 +0300 Subject: wifi: cfg80211: add link id to txq params The Tx queue parameters are per link, so add the link ID from nl80211 parameters to the API. While at it, lock the wdev when calling into the driver so it (and we) can check the link ID appropriately.
