+/**
+ * struct caif_dev_common - data shared between CAIF drivers and stack.
+ * @flowctrl:          Flow Control callback function. This function is
+ *                      supplied by CAIF Core Stack and is used by CAIF
+ *                      Link Layer to send flow-stop to CAIF Core.
+ *                      The flow information will be distributed to all
+ *                      clients of CAIF.
+ *
+ * @link_select:       Profile of device, either high-bandwidth or
+ *                     low-latency. This member is set by CAIF Link
+ *                     Layer Device in order to indicate if this device
+ *                     is a high bandwidth or low latency device.
+ *
+ * @use_frag:          CAIF Frames may be fragmented.
+ *                     Is set by CAIF Link Layer in order to indicate if the
+ *                     interface receives fragmented frames that must be
+ *                     assembled by CAIF Core Layer.
+ *
+ * @use_fcs:           Indicate if Frame CheckSum (fcs) is used.
+ *                     Is set if the physical interface is
+ *                     using Frame Checksum on the CAIF Frames.
+ *
+ * @use_stx:           Indicate STart of frame eXtension (stx) in use.
+ *                     Is set if the CAIF Link Layer expects
+ *                     CAIF Frames to start with the STX byte.
+ *
+ * This structure is shared between the CAIF drivers and the CAIF stack.
+ * It is used by the device to register its behavior.
+ * CAIF Core layer must set the member flowctrl in order to supply
+ * CAIF Link Layer with the flow control function.
