From 55167a3eed53ce8b40d5bf2a3e0be4e15d2eba57 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 29 Jan 2024 20:35:45 +0100 Subject: wifi: mac80211: allow CSA to same channel This could be used e.g. for temporarily sending quiet (mode=1 in CSA/ECSA), or updating bandwidth. This is also useful for testing, since it's something that an AP may do and the client needs to be prepared. Simply allow it.
