From f019f4dff2e4cb8704dc608496e3f2829de3e919 Mon Sep 17 00:00:00 2001 From: Carl Huang Date: Wed, 14 Feb 2024 10:38:10 +0200 Subject: [PATCH] wifi: ath11k: support 2 station interfaces Add hardware parameter support_dual_stations to indicate whether 2 station interfaces are supported. For chips which support this feature, limit total number of AP interface and mesh point to 1. The max interfaces are 3 for such chips. The chips affected are: QCA6390 hw2.0 WCN6855 hw2.0 WCN6855 hw2.1 Other chips are not affected. For affected chips, remove radar_detect_widths because now num_different_channels is set to 2. radar_detect_widths can be set only when num_different_channels is 1, see mac80211 function wiphy_verify_combinations for details. This means that in affectected chips DFS cannot be enabled in AP mode.
