From de3afeafbc5397711eb1c22367d286bd02dbcaab Mon Sep 17 00:00:00 2001 From: Howard Hsu Date: Mon, 27 Jul 2026 15:04:31 +0000 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.
