Currently there are limitations in the virthcnl.h interface that only allow a maximum of 16 queues to be used by a VF driver. Add support in virtchnl.h to allow a VF driver to request >16 queues. Also, the RSS qregion size is currently assumed to be the max number of queues a VF can request and/or is given on initialization. With larger VFs this assumption can no longer be made, so add a new op to support querying the max RSS qregion size. In order to request more queues than the initially given queues the VF driver needs to use the VIRTCHNL_OP_REQUEST_QUEUES opcode. The VF is given more >16 queues it should use the new VIRTCHNL_OP_GET_MAX_RSS_QREGION to determine its max qregion size. This is needed to correctly configure the RSS LUT and/or configure filters based on queue base/offset and queue region size. If the VF is configuring >16 queues it should use the following opcodes to configure the qeueus and interrupts after successfully requesting them. VIRTCHNL_OP_MAP_QUEUE_VECTOR VIRTCHNL_OP_ENABLE_QUEUES_V2 VIRTCHNL_OP_DISABLE_QUEUES_V2 Also, add support in virtchnl_vc_validate_vf_msg() to validate the above messages. As a part of this move the virtchnl_vector_limits enumeration directly above the function it's used. The patch also update base code release version in readme.
