-Subject: [PATCH 77/91] net: mediatek: do not set the QID field in the TX DMA
- descriptors
-
-The QID field gets set to the mac id. This made the DMA linked list queue
-the traffic of each MAC on a different internal queue. However during long
-term testing we found that this will cause traffic stalls as the multi
-queue setup requires a more complete initialisation which is not part of
-the upstream driver yet.
-
-This patch removes the code setting the QID field, resulting in all
-traffic ending up in queue 0 which works without any special setup.
