- 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.

- 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

- * 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.
