NAME
isp - Qlogic based SCSI and FibreChannel SCSI Host Adapters
SYNOPSIS
isp* at pci? dev? function? (PCI)
isp* at sbus? slot ? offset ? (SBus)
scsibus* at isp?
DESCRIPTION
This driver provides access to SCSI or FibreChannel devices.
SCSI features include support for Ultra SCSI and wide mode transactions
for SCSI, and LVD (for the ISP1080 and ISP1280),
Fibre Channel support uses FCP SCSI profile for FibreChannel. and uti-
lizes Class 3 connections only. Support is available for Public and Pri-
vate loops. Command tagging is supported for all (in fact, FibreChannel
requires tagging).
CONFIGURATION
An optional flags 0x80 appended to the above isp* declarations will dis-
able the download of driver f/w, which means you use whatever F/W is run-
ning on the card. If no firmware is running on the card, the driver can-
not operate the card.
An optional flags 0x40 appended to the above isp* declarations (can be
OR'd in with the other config flags option) will keep the driver from
looking at device or bus NVRAM settings (this is in case NVRAM is just
wrong and you have the card in a platform where it is inconvenient to
change NVRAM settings on the card).

BUGS
The driver currently ignores some NVRAM settings.
The driver currently doesn't do error recovery for timed out commands
very gracefully.
Fabric (public loop) support isn't very well debugged yet.
Sometimes, when booting, the driver gets stuck waiting for the Fibre
Channel f/w to tell it that the loop port database is ready. In this case
you'll see an announcement that the loop state has a value of 0x1. To un-
wedge the system, unplug and replug the fibre channel connection, or oth-
erwise cause a LIP (Loop Initialization Primitive sequence)- this will
kick the f/w into getting unstuck.
