32 bit handles. The RIO (reduced interrupt operation) and fast posting
for the parallel SCSI cards were all 16 bit handles. Furthermore,
target mode parallel SCSI only can have 16 bit handles.
Use part of a supplied patch to switch over to using 32 bit handles.
Be a bit more conservative here and only do this for parallel SCSI
for the 12160 (Ultra3) cards. There were a lot of marginal Ultra2
cards, and, frankly, few are findable now for testing.
Fix the target handle routine to only do 16 bit handles for parallel
SCSI cards. This is okay because the upper sixteen bits of the new
32 bit handles is a sequence number to help protect against duplicate
completions. This would be very unlikely to happen with parallel
SCSI target mode, and wasn't present before, so we're no worse off
than we used to be.
While we're at it, finally split the async mailbox completion handlers
into FC and parallel SCSI functions. This makes it much cleaner and
easier to figure out what is or isn't a legal async mailbox completion
code for different card classes.

numbers and handle types in rational way. This will better protect from
(unwittingly) dealing with stale handles/commands.
Fix the watchdog timeout code to better protect itself from mistakes.
If we run an abort on a putatively timed out command, the command
may in fact get completed, so check to make sure the command we're
timing it out is still around. If the abort succeeds, btw, the command
should get returned via a different path.
firmware loading bugs.
Target mode support has received some serious attention to make it
more usable and stable.
Some backward compatible additions to CAM have been made that make
target mode async events easier to deal with have also been put
into place.
Further refinement and better support for NP-IV (N-port Virtualization)
is now in place.
Code for release prior to RELENG_7 has been stripped away for code clarity.

First, we were never correctly checking for a 24XX Status Type 0
response- that cased us to fall through to evaluate status for
commands as if this were a 2100/2200/2300 Status Type 0 response.
This is *close*, but not quite the same. This has been reported
to be apparent with some wierd lun configuration problems with
some arrays. It became glaringly apparent on sparc64 where none
of the correct byte swap things were done.
Fixing this omission then caused a whole universe shifting debug
cycle of endian issues for the 2400. The manual for 24XX f/w turns
out to be wrong about the endianness of a couple of entities. The
lun and cdb fields for the type 7 request are *not* unconditionally
big endian- they happen to be opposite of whatever the endian of
the current machine type is. Same with the sense data for the
24XX type 0 response.
While we're at it investigate and resolve some NVRAM endian
issues.

When the linux port changes were imported which split the
target command list to be separate from the initiator command
list and the handle format changed to encode a type in the handle
the implications to the function isp_handle_index (which only
the NetBSD/OpenBSD/FreeBSD ports use) were overlooked.
The fault is twofold: first, the index into the DMA maps
in isp_pci is wrong because a target command handle with
the type bit left in place caused a bad index (and panic)
into dma map. Secondly, the assumption of the array
of DMA maps in either PCS or SBUS attachment structures is
that there is a linear mapping between handle index and
DMA map index. This can no longer be true if there are
overlapping index spaces for initiator mode and target
mode commands.
These changes bandaid around the problem by forcing us
to not have simultaneous dual roles and doing the appropriate
masking to make sure things are indexed correctly. A longer
term fix is being devloped.

change_is_bad- whether or not to accept devices with the same
WWNN/WWPN that reappear at a different PortID as being the 'same'
device.
Keen students of some of the subtle issues here will ask how
one can keep devices from being re-accepted at all (the answer
is to set a gone_device_time to zero- that effectively would
be the same thing).

b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two

on this in a week or so.
