So far we have been using only one queue (i.e. default flow) for all RX traffic. This series adds multi-queue support. The driver starts with 1 RX queue by default. User can increase the RX queues via ethtool, e.g. 'ethtool -L ethx rx ' The series also adds regmap and regfield support to some of the ALE registers. It adds Policer/Classifier registers and fields. Converting the existing ALE control APIs to regfields can be a separate exercise. Some helper functions are added to read/write to the Policer/Classifier registers and a default Classifier setup function is added that routes packets based on their PCP/DSCP priority to different RX queues.
