cxgb4: add FLOWC based QoS offload
Rework SCHED API to allow offloading TC-MQPRIO QoS configuration. The existing QUEUE based rate limiting throttles all queues sharing a traffic class, to the specified max rate limit value. So, if multiple queues share a traffic class, then all the queues get the aggregate specified max rate limit. So, introduce the new FLOWC based rate limiting, where multiple queues can share a traffic class with each queue getting its own individual specified max rate limit. For example, if 2 queues are bound to class 0, which is rate limited to 1 Gbps, then 2 queues using QUEUE based rate limiting, get the aggregate output of 1 Gbps only. In FLOWC based rate limiting, each queue gets its own output of max 1 Gbps each; i.e. 2 queues * 1 Gbps rate limit = 2 Gbps.
