Subject: [PATCH 6/8] mt76: only mark tx-status-failed frames as ACKed on mt76x0/2
Date: Tue, 11 Mar 2025 11:36:43 +0100 [thread overview]
Message-ID: <20250311103646.43346-6-nbd@nbd.name> (raw)
In-Reply-To: <20250311103646.43346-1-nbd@nbd.name>
The interrupt status polling is unreliable, which can cause status events
to get lost. On all newer chips, txs-timeout is an indication that the
packet was either never sent, or never acked.
Fixes issues with inactivity polling.
