	help
	  Set the number of Isochronous Rx SDU fragments to be buffered in the
	  ISO-AL per channel. Buffering is required to compute the size of the
	  received SDU across all the fragments before each is released. The
	  number of buffers and maximum SDU fragment size will limit the maximum
	  size of an SDU that can be accurately declared in the HCI ISO Data
	  header.

	  Minimum number of payload bytes that would make inserting a new
	  segment into a PDU worthwhile.

	  Needed margin for reliable delivery of payloads will vary, but should
	  generally be EVENT_OVERHEAD_START_US + a small margin to cover ISOAL
	  processing overhead

config BT_CTLR_ISOAL_FRAMED_CIS_OFFSET_MARGIN

	  Note: Usually no margin is needed for CIS as Null PDUs can be used if a payload
	  is too late for the first subevent
