From f72311544089f780802e7b16a363ccbc4afe2501 Mon Sep 17 00:00:00 2001 From: Howard Hsu Date: Fri, 24 Jul 2026 21:11:30 +0200 Subject: [PATCH] wifi: mt76: mt7996: reject iTWT setup requests from MLD stations The firmware does not support individual TWT agreements with non-AP MLDs, and the driver only tracks TWT flow state on the default link, which may not be the link the agreement was negotiated on. Reject TWT setup requests from MLD stations instead of programming an unsupported configuration.
