net/sched: move struct tc_mqprio_qopt_offload from pkt_cls.h to pkt_sched.h Since mqprio is a scheduler and not a classifier, move its offload structure to pkt_sched.h, where struct tc_taprio_qopt_offload also lies. Also update some header inclusions in drivers that access this structure, to the best of my abilities.

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.

cxgb4: add ETHOFLD hardware queue support Add support for configuring and managing ETHOFLD hardware queues. Keep the queue count and MSI-X allocation scheme same as NIC queues. ETHOFLD hardware queues are dynamically allocated/destroyed as TC-MQPRIO Qdisc offload is enabled/disabled on the corresponding interface, respectively.

cxgb4: parse and configure TC-MQPRIO offload Add logic for validation and configuration of TC-MQPRIO Qdisc offload. Also, add support to manage EOSW_TXQ, which have 1-to-1 mapping with EOTIDs, and expose them to network stack. Move common skb validation in Tx path to a separate function and add minimal Tx path for ETHOFLD. Update Tx queue selection to return normal NIC Txq to send traffic pattern that can't go through ETHOFLD Tx path.
