From 4ace04c0bdbde3b028ec0a5a3be2471cdb1efb67 Mon Sep 17 00:00:00 2001 From: Aditya Kumar Singh Date: Tue, 30 Jan 2024 19:39:14 +0530 Subject: [PATCH] wifi: cfg80211: send link id in channel_switch ops Currently, during channel switch, no link id information is passed down. In order to support channel switch during Multi Link Operation, it is required to pass link id as well. Add changes to pass link id in the channel_switch cfg80211_ops.
