| H A D | nfc-hci.rst | 153 currently two modules : nop (raw transfer) and shdlc.
193 shdlc is included.
201 the current llc. In case of shdlc, the frame is queued in shdlc rx queue.
205 Only when llc_shdlc is used: handles shdlc rx & tx queues.
223 Workflow executing an HCI command (using shdlc)
243 to the lower layer which happens to be shdlc. It will then start a timer to be
247 handles shdlc framing in and out. It uses the driver xmit to send frames and
293 problem above. shdlc stores a EREMOTEIO sticky status, which will trigger
296 - SMW is basically a background thread to handle incoming and outgoing shdlc
297 frames. This thread will also check the shdlc sticky status and report to HCI
