From b4dcf43dfee61418560de6a77016ca6c47cedac7 Mon Sep 17 00:00:00 2001 From: Kieran Frewen Date: Wed, 20 Apr 2022 04:13:20 +0000 Subject: [PATCH] cfg80211: retrieve S1G operating channel number When retrieving the S1G channel number from IEs, we should retrieve the operating channel instead of the primary channel. The S1G operation element specifies the main channel of operation as the oper channel, unlike for HT and HE which specify their main channel of operation as the primary channel.
