The port 5 of the qca8337 have some problem in flood condition. The original legacy driver had some specific buffer and priority settings for the different port suggested by the QCA switch team. Add this missing settings to improve switch stability under load condition. The packet priority tweak is only needed for the qca8337 switch and other qca8k switch are not affected.
