This patch adds new virtchnl opcodes and structures for QoS configuration, which includes: 1. VIRTCHNL_VF_OFFLOAD_TC, to negotiate the capability supporting QoS configuration. If VF and PF both have this flag, then the ETS-based QoS offload function is supported. 2. VIRTCHNL_OP_DCF_CONFIG_BW, DCF is supposed to configure min and max bandwidth for each VF per enabled TCs. To make the VSI node bandwidth configuration work, DCF also needs to configure TC node bandwidth directly. 3. VIRTCHNL_OP_GET_QOS_CAPS, VF queries current QoS configuration, such as enabled TCs, arbiter type, up2tc and bandwidth of VSI node. The configuration is previously set by DCB and DCF, and now is the potential QoS capability of VF. VF can take it as reference to configure queue TC mapping. 4. VIRTCHNL_OP_CONFIG_TC_MAP, set VF queues to TC mapping for all Tx and Rx queues. Queues mapping to one TC should be continuous and all allocated queues should be mapped.
