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.
