-/* 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.

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the drivers for all devices starting from our 40G product line
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * The 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 status_code type, defined in the shared 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.
