+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of these
+ * opcodes. The VF driver must first validate the API version of the PF driver,
+ * then request a reset, then get resources, then configure queues and
+ * interrupts. After these operations are complete, the VF driver may start
+ * its queues, optionally add MAC and VLAN filters, and process traffic.

* Returns information about every available sensor.
+ *
+ * Each sensor has a single (16bit) value, and a corresponding state. The
+ * mapping between value and state is nominally determined by the MC, but may
+ * be implemented using up to 2 ranges per sensor.
+ *
+ * This call returns a mask (32bit) of the sensors that are supported by this
+ * platform, then an array of sensor information structures, in order of sensor
+ * type (but without gaps for unimplemented sensors). Each structure defines
+ * the ranges for the corresponding sensor. An unused range is indicated by
+ * equal limit values. If one range is used, a value outside that range results
+ * in STATE_FATAL. If two ranges are used, a value outside the second range
+ * results in STATE_FATAL while a value outside the first and inside the second
+ * range results in STATE_WARNING.
+ *
+ * Sensor masks and sensor information arrays are organised into pages. For
+ * backward compatibility, older host software can only use sensors in page 0.
+ * Bit 32 in the sensor mask was previously unused, and is no reserved for use
+ * as the next page flag.
+ *
+ * If the request does not contain a PAGE value then firmware will only return
+ * page 0 of sensor information, with bit 31 in the sensor mask cleared.
+ *
+ * If the request contains a PAGE value then firmware responds with the sensor
+ * mask and sensor information array for that page of sensors. In this case bit
+ * 31 in the mask is set if another page exists.
