51  * A few words on the waiting SCB list:
55  * SCB that we've already pulled from the QINFIFO and started the selection
59  * create yet another SCB waiting for selection.  The solution used here is to 
60  * use byte 27 of the SCB as a pseudo-next pointer and to thread a list
61  * of SCBs that are awaiting selection.  Since 0-0xfe are valid SCB indexes, 
64  * command for which a second SCB has been queued.  The sequencer will
104 	 * We have at least one queued SCB now and we don't have any 
106 	 * card SCB for the host's SCB and get to work on it.
111 		/* In the non-paging case, the SCBID == hardware SCB index */
118 	 * DMA the SCB from host ram into the current SCB location.
123 	 * Check one last time to see if this SCB was canceled
147 	 * Start the first entry on the waiting SCB list.
393  * Initialize transfer settings with SCB provided settings.
429  * After the selection, remove this SCB from the "waiting SCB"
432  * SCB is used, so don't bother with it now.
449 		 * all connections have an SCB.
749 	 * sure we don't have an SCB prefetch going on.
852 	 * Initialize the DMA address and counter from the SCB.
855 	 * modify the saved values in the SCB until we see a save
1199 			 * Workaround for flaky external SCB RAM
1202 			 * S/G ram to certain SCB locations.
1277 	 * the SCB.  We use STCNT instead of HCNT, since it's a reflection
1418 			 * data from external SCB memory into
1465  * and store it into the SCB.
1477  * override this behavior by setting the MK_MESSAGE bit in the SCB
1487  * on an SCB that might not be for the current nexus. (For example, a
1489  * an SCB that doesn't have anything to do with the current target).
1514  * Send a tag message if TAG_ENB is set in the SCB control block.
1515  * Use SCB_TAG (the position in the kernel's SCB array) as the tag value.
1605  * In either of these conditions, we upload the SCB back to the host so it can
1609  * sense, it will fill the kernel SCB with a request sense command, requeue
1693  * Is it a disconnect message?  Set a flag in the SCB to remind us
1695  * store the SCB id for it in our untagged target table for lookup on

1775  * SCB anytime we enter a data phase for the first time, so all
1805  * that the reconnection is for - find the correct SCB and switch to it,
1863 			 * findSCB removes the SCB from the
1865 			 * it there should this SCB be for another
1875  * SCB.  With SCB paging, we must search for non-tagged
1876  * transactions since the SCB may exist in any slot.  If we're not
1877  * using SCB paging, we can use the tag as the direct index to the
1878  * SCB.
1904  * Ensure that the SCB the tag points to is for
1905  * an SCB transaction to the reconnecting target.
2037  * Locate a disconnected SCB by SCBID.  Upon return, SCBPTR and SINDEX will
2038  * be set to the position of the SCB.  If the SCB cannot be found locally,

2041  * removal of the found SCB from the disconnected list.

2191  * Either post or fetch an SCB from host memory based on the
2192  * DIRECTION bit in DMAPARAMS. The host SCB index is in SINDEX.
2236 		/* Fill it with the SCB data */
2337  * Restore an SCB that failed to match an incoming reselection
2338  * to the correct/safe state.  If the SCB is for a disconnected
