Add support for 2 Gigabit cards (2300/2312). This necessitated a change
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).
Rearchitect how regular SCSI parameters are stored or used.

ISPCTL_RUN_MBOXCMD entry point. Add ISPASYNC_UNHANDLED_RESPONSE
definition.

isp_iid_set/isp_iid for fibre channel- this is because we now
fake a port database entry for ourselves. Add the additional loop
states between LOOP_PDB_RCVD and LOOP_READY.
Change and comment on a wad of Fibre Channel isp_control functions.
Change and comment on some of the ISPASYNC Fibre Channel events.
Add was_fabric_dev/fabric_dev tags to our local FC database structure
(so we can see rapidly whether something was a fabric device but is
now gone).
Add a tag which says what role this adapter should take. It can take
on the value of None, Target, Initiator or Both. None is useful for
warm failover purposes. Remove the ISP_CFG_NOINIT silliness since
a role of "None" does this.
Add a isp_lastmbxcmd tag to store the opcode for the last mailbox
command used.

the async code event changes. Note (for __GNUC__) that isp_prt has
__attributes__'s of __format__/__printf__....

instrumentation for interrupts, specific topology preferences for
the 2200. Fix the hole in the OpenBSD port becuause there'd been
no maxluns limit from the midlayer and have the command routine
bounce commands > the maxluns for a particular controller (in
particular, Qlogic FC cards where we can't tell when it hasn't been
us that have loaded the F/W whether or not SCCLUN is in effect
or not).

Major rewrite of a lot of internals- far too many to list. Cleaner
locking, more paramaterization, an isp_prt logging function that
handles debugging as well as error printouts. We also should no
longer hang if there is no Loop for Fibre Channel when booting.
The file ispvar.h now contains a list of all platform required macros
and explanation as to what they're for. This should make maintenance
easier.

routines are not necessarily polled now- this should cut down on some of
the spurious lost commands that have occurred. Also, we now watchdog each
command and make sure that command constipation doesn't occur (which it
has been documented to do on the QLA2100 cards).

and definitions.

Do some SNS fabric suppor tchanges. Roll revision levels. Tested on
GENERIC i386 && sparc.

and add in IS_DUALBUS and IS_ULTRA2 macros.
