- * command with up to 4 scatter/gather entries.  If we need more
- * than 4 entries, continuation entries can be used that hold
- * another 7 entries each.  Unlike for other drivers, this means
- * that the maximum number of scatter/gather entries we can
- * support at any given time is a function of the number of queue
- * slots available.  That is, host->can_queue and host->sg_tablesize
- * are dynamic and _not_ independent.  This all works fine because
- * requests are queued serially and the scatter/gather limit is
- * determined for each queue request anew.
