Hi,
am65-cpsw can support up to 8 queues at Rx. 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 ethx -L rx <N>'
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.
'RFC' because I had to revert the RX coalesing patch [1] to
apply this series. I still need to work out how this will work
together with RX coalescing. Series is based on v6.9
