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.
