| 16 | * struct caif_dev_common - data shared between CAIF drivers and stack. | ||
| 17 | * @flowctrl: Flow Control callback function. This function is | ||
| 18 | * supplied by CAIF Core Stack and is used by CAIF | ||
| 19 | * Link Layer to send flow-stop to CAIF Core. | ||
| 20 | * The flow information will be distributed to all | ||
| 21 | * clients of CAIF. | ||
| 22 | * | ||
| 23 | * @link_select: Profile of device, either high-bandwidth or | ||
| 24 | * low-latency. This member is set by CAIF Link | ||
| 25 | * Layer Device in order to indicate if this device | ||
| 26 | * is a high bandwidth or low latency device. | ||
| 27 | * | ||
| 28 | * @use_frag: CAIF Frames may be fragmented. | ||
| 29 | * Is set by CAIF Link Layer in order to indicate if the | ||
| 30 | * interface receives fragmented frames that must be | ||
| 31 | * assembled by CAIF Core Layer. | ||
| 32 | * | ||
| 33 | * @use_fcs: Indicate if Frame CheckSum (fcs) is used. | ||
| 34 | * Is set if the physical interface is | ||
| 35 | * using Frame Checksum on the CAIF Frames. | ||
| 36 | * | ||
| 37 | * @use_stx: Indicate STart of frame eXtension (stx) in use. | ||
| 38 | * Is set if the CAIF Link Layer expects | ||
| 39 | * CAIF Frames to start with the STX byte. | ||
| 40 | * | ||
| 41 | * This structure is shared between the CAIF drivers and the CAIF stack. | ||
| 42 | * It is used by the device to register its behavior. | ||
| 43 | * CAIF Core layer must set the member flowctrl in order to supply | ||
| 44 | * CAIF Link Layer with the flow control function. | ||
