From c27bb624b3d789a337df3bbcc020a575680555cc Mon Sep 17 00:00:00 2001 From: Thiraviyam Mariyappan Date: Sun, 8 Jun 2025 20:26:51 +0530 Subject: [PATCH] wifi: ath12k: Clear auth flag only for actual association in security mode When setting a new bitrate, WMI peer association command is sent from the host without the peer authentication bit set in peer_flags for security mode, which causes ping failure. The firmware handles peer_flags when the client is associating, as the peer authentication bit in peer_flags is set after the key exchange. When the WMI peer association command is sent from the host to update the new bitrate for an associated STA, the firmware expects the WMI peer authentication bit to be set in peer_flags. Fix this issue by ensuring that the WMI peer auth bit is set in peer_flags in WMI peer association command when updating the new bitrate.
