From 3f6e6c3291ed9ebf459b76666c7c6e379de3278e Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Tue, 29 Sep 2020 20:15:33 +0300 Subject: [PATCH] ath11k: disable monitor mode on QCA6390 QCA6390 does not support monitor mode at the moment so disable it altogether, using a hack as mac80211 does not support disabling it otherwise. Add a boolean to hw_params to know if hardware supports monitor mode. IPQ8074 continues to support monitor mode normally.
