From 54f40f552afd5a07e635a52221ec4b0ce765c374 Mon Sep 17 00:00:00 2001 From: Wen Gong Date: Tue, 28 Sep 2021 14:00:43 +0300 Subject: [PATCH] ath11k: re-enable ht_cap/vht_cap for 5G band for WCN6855 WCN6855 uses single_pdev_only, so it supports both the 5G and 6G bands in the same ath11k/pdev and it needs to enable ht_cap/vht_cap for the 5G band, otherwise it will downgrade to non-HT mode for the 5G band. Some chips like QCN9074 only support the 6G band, not the 5G band, and use the flag ar->supports_6ghz which is true to discard ht_cap/vht_cap.
