+What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
+Date: June 2007 (scheduled), removed in kernel v2.6.23
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
+ been deprecated for quite some time. They are very inefficient as they
+ come with high interrupt load and several layers of callbacks for each
+ packet. Because of these deficiencies, the video1394 and dv1394 drivers
+ and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
+
+Users:
+ libraw1394 users via the long deprecated API raw1394_iso_write,
+ raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
+
+ libdc1394, which optionally uses these old libraw1394 calls
+ alternatively to the more efficient video1394 ABI
