10 Fibre Channel is a high speed serial protocol mainly used to
11 connect large storage devices to the computer; it is compatible with
12 and intended to replace SCSI.
13
14 This is an experimental support for storage arrays connected to your
15 computer using optical fibre cables and the "X3.269-199X Fibre
16 Channel Protocol for SCSI" specification. If you want to use this,
17 you need to say Y here and to "SCSI support" as well as to the
18 drivers for the storage array itself and for the interface adapter
19 such as SOC or SOC+. This subsystem could even serve for IP
20 networking, with some code extensions.
21
22 If unsure, say N.

31 Serial Optical Channel is an interface card with one or two Fibre
32 Optic ports, each of which can be connected to a disk array. Note
33 that if you have older firmware in the card, you'll need the
34 microcode from the Solaris driver to make it work.
35
36 To compile this support as a module, choose M here: the module will
37 be called soc.

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

6 * There are two kinds of Fibre Channel adapters used in Linux. Either
7 * the adapter is "smart" and does all FC bookkeeping by itself and
8 * just presents a standard SCSI interface to the operating system
9 * (that's e.g. the case with Qlogic FC cards), or leaves most of the FC
10 * bookkeeping to the OS (e.g. soc, socal). Drivers for the former adapters
11 * will look like normal SCSI drivers (with the exception of max_id will be
12 * usually 127), the latter on the other side allows SCSI, IP over FC and other
13 * protocols. This driver tree is for the latter adapters.
14 *
15 * This file should support both Point-to-Point and Arbitrated Loop topologies.

12 * For SOC sbus cards, you have to make sure your FCode is 1.52 or later.
13 * If you have older FCode, you should try to upgrade or get SOC microcode from Sun
14 * (the microcode is present in Solaris soc driver as well). In that case you need
15 * to #define HAVE_SOC_UCODE and format the microcode into soc_asm.c. For the exact
