         cmd_per_lun=#tags (#tags > 1) tagged command queuing enabled
   #tags will be truncated to the max queued commands configuration parameter.
 
-10.2.2  Detailed control of tagged commands
-  This option allows you to specify a command queue depth for each device 
-  that supports tagged command queueing.
-  Example:
-      tag_ctrl=10/t2t3q16-t5q24/t1u2q32
-  will set devices queue depth as follow:
-      - controller #0 target #2 and target #3                  -> 16 commands,
-      - controller #0 target #5                                -> 24 commands,
-      - controller #1 target #1 logical unit #2                -> 32 commands,
-      - all other logical units (all targets, all controllers) -> 10 commands.
-
-10.2.3 Burst max
+10.2.2 Burst max
         burst=0    burst disabled
         burst=255  get burst length from initial IO register settings.
         burst=#x   burst enabled (1<<#x burst transfers max)
   #x is an integer value which is log base 2 of the burst transfers max.
   By default the driver uses the maximum value supported by the chip.
 
-10.2.4 LED support
+10.2.3 LED support
         led=1      enable  LED support
         led=0      disable LED support
   Do not enable LED support if your scsi board does not use SDMS BIOS.

 As a result of the new module parameters, this is no longer available.
-Most of the options have remained the same, but tags has split into
-cmd_per_lun and tag_ctrl for its two different purposes.  The sample above

-	tristate "Fibre Channel and FC4 SCSI support"
-	---help---
-	  Fibre Channel is a high speed serial protocol mainly used to
-	  connect large storage devices to the computer; it is compatible with
-	  and intended to replace SCSI.
-
-	  This is an experimental support for storage arrays connected to your
-	  computer using optical fibre cables and the "X3.269-199X Fibre
-	  Channel Protocol for SCSI" specification. If you want to use this,
-	  you need to say Y here and to "SCSI support" as well as to the
-	  drivers for the storage array itself and for the interface adapter
-	  such as SOC or SOC+. This subsystem could even serve for IP
-	  networking, with some code extensions.
-
-	  If unsure, say N.

-	  Serial Optical Channel is an interface card with one or two Fibre
-	  Optic ports, each of which can be connected to a disk array. Note
-	  that if you have older firmware in the card, you'll need the
-	  microcode from the Solaris driver to make it work.
-
-	  To compile this support as a module, choose M here: the module will
-	  be called soc.

-	tristate "Sun SOC+ (aka SOCAL)"

-	---help---
-	  Serial Optical Channel Plus is an interface card with up to two
-	  Fibre Optic ports. This card supports FC Arbitrated Loop (usually
-	  A5000 or internal FC disks in E[3-6]000 machines through the
-	  Interface Board). You'll probably need the microcode from the
-	  Solaris driver to make it work.

- * There are two kinds of Fibre Channel adapters used in Linux. Either
- * the adapter is "smart" and does all FC bookkeeping by itself and
- * just presents a standard SCSI interface to the operating system
- * (that's e.g. the case with Qlogic FC cards), or leaves most of the FC
- * bookkeeping to the OS (e.g. soc, socal). Drivers for the former adapters
- * will look like normal SCSI drivers (with the exception of max_id will be
- * usually 127), the latter on the other side allows SCSI, IP over FC and other
- * protocols. This driver tree is for the latter adapters.
- *
- * This file should support both Point-to-Point and Arbitrated Loop topologies.
