/**
* 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 .
