 * 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
