also in. Other work in progress.

Add support for up through 2.6.25 (might even be good for 2.6.26)
Remove HBAAPI support. This never has worked well and I doubt anyone will miss it.
Remove files not pertinent SCST build.

The patch below implements the following changes:
- Fixes the remaining warnings reported by checkpatch.pl with regard to the use
of whitespace in C code.
- Adds double qoutes around some #warning messages, such that checkpatch.pl
does no longer try to interprete the text behind the #warning preprocessor
directive.
- Adds an extra conversion to the generate-kernel-patch script that removes
the single space from before goto-labels while generating the kernel patch.
This patch has been tested as follows:
- Verified that svn diff -x -w only shows changes in the #warning preprocessor directives.
- Verified the output of svn diff by reading it.
- Verified that checkpatch.pl does no longer complain on the use of whitespace
(searched through the checkpatch.pl output for the text ' space').
- Verified that the patch generated by the generate-kernel-patch script still
applies cleanly to the 2.6.24 kernel, and that the patched kernel still compiles cleanly.
Please let me know if I have to resubmit parts of this patch to other SCST authors.

One of the Linux kernel patch submission requirements is that source files do
not contain trailing whitespace. The patch below removes trailing whitespace
from .c and .h source files.
Note: it might be more convenient to run the script I used to generate this
patch than to review and apply the patch below. This is how I generated and
verified the patch below:
cat <<EOF >./strip-trailing-whitespace
#!/bin/bash
trap "rm -f $t" EXIT
t=/tmp/temporary-file.$$
for f in "$@"
do
sed 's/[ ]*$//' <"$f" >"$t" && mv "$t" "$f"
done
EOF
chmod a+x ./strip-trailing-whitespace
find -name '*.[ch]' | xargs ./strip-trailing-whitespace
svn diff -x -w

- Make FC_SCRATCH_ACQUIRE a macro that returns true/false
- Fixes from Stanislaw for 2.6.23 & 2.6.24. Many thanks.
- A quick hack to isp_kthread to use waitqueues instead of semaphores
to have less blockage. More rewrites later

- whitespace and other minor fixes
- Remove F/W crash dump support. We only worked it out for 2200 and 2300
cards. It's also true that QLogic would not support us even if we *did*
give them a crash dump, so the usage here is not really worth it.

I don't know why I thought this would work- forcing a re-login to the fabric
controller just barfs.
Make down count reflect jiffies elapsed rather than depend on calls to
ISP_FC_RESCAN.
Shorten deadloop time default to 10 seconds.
At least enable MSI (if not MSI-X) for 24XX cards.

We can (somehow) get commands on an atio7 for which we've never had a PLOGI/PRLI.
How this happens, I don't know. Anyway, we stick a tentative entry in the PDB
and call the task thread to find the rest of the info. This includes, badly and
stupidly, searching for the N-port handle by asking the chip. Sometimes it's not
there. In that case, we terminate the command.
In restarting commands that arrive while we start up, have the watchdog
time call isp_task_thread- this gives us a bit of hysteresis.

Make 2100/2200 and 2300 cards also maintain a target mode port database.
For the 24XX, we have to find the IID, N-port handle and channel when we
get an ATIO7. For the other cards, we already have the channel and N-port
handle and Port IID of the initiator, but have to find the S_ID.
Do the isp_find_pdb_by_{sid,loopid} functions search backwards to minimize
search time.
Don't load fw images more than once per device type!

Put RISC_CODE define in the firmware files.
Use the Linux 2.6 firmware loader support if available. This saves
close to 700K of useless code getting loaded otherwise.

Note that asking for "prefer N-port and then Loop" with the 24XX seems to
cause the f/w to crash. So, don't do that.
Firmware crashes are now considered fatal and cause the HBA to be marked dead.
Now that we've avoided the f/w crash in isp_init_24xx, we can process
toplogy options.

Don't use both WWNs in the ICB block unless they're not NAA==2. This makes us
more consistent with QLogic driver setups and thus more likely to fit into the
same zoning setups.
If we're getting a PDB and it's for the Fabric Controller, force a login
to it (just in case it logged out underneath us). Return 'not logged in'
for the 24XX in case the 24XX specific login state isn't in the range of
PLOGI_DONE to LOGGED IN.
Don't do local loop scans if we have more than one channel (NP-IV) and we're
in a FL-port topology- we just end up poking ourselves usually.
Make sure we set loopstate in a couple of places we missed so that we
try and get it again.
Add in the RESET DEVICE and ABORT COMMAND functions for the 24XX cards
(finally).
Fix a longstanding bug where were passing the wrong (off by one) output
pointer to isp_handle_other_response.
Change isp_async...ISPASYNC_CHANGE_NOTIFY to have N-port handle, nlstate and
reason included as we get these for free with PDB Changed stuff for the
24XX card. Eventually we should be able to edit single local PDB entry
states instead of doing a full eval.
Put in the put of a 24XX Task Management Function IOCB. There is no get because
the firmware doesn't return it when done- instead a status iocb is done.
There is no "FAST POST" flag for the 24XX- this is a NOACK flag which means
that there is no interrupt if all goes well.
Fix spelling mistakes.
In isp_add_wwn_entry, ahem, don't allocate PDB entries out of the 'rexerved
for chip' area.
Put more comments in as to why we're terminating an exchange (and make them
all ISP_LOGTINFO).
Add, finally, the correct handling for a QIN_NOTIFY_ACK for a task management
function- this means we construct a ct7_entry_t to get the firmware to send
an FC Response IU for it. So, finally LUN RESETS and TARGET RESETS and
ABORT TASK will actually work and, more importantly, be seen to be working
by initiators.
Fix WWN defaults/active generation and retrieval. It was broken.

Add unit attention injection. Fix some ridiculous Sense things.
Say why we couldn't pci register the driver.
Make isp_thread_event return an int if it fails to send the event. If it
fails to send the event, and this was for the 24XX card finding out the
initiator for a command, return the command with a BUSY status.
An N-port handle of zero is legal for a 24XX.
Add some more special N-Port handle definitions for 2K f/w.

As of version 4.0.25 the vpindex is available for MID f/w on the 24XX
for ASYNC_CHANGE_NOTIFY in outgoing mailbox 3.
Per QLogic release notes, the immediate notify entry for the 24XX has
various other items of interest in it based upon the ELS code.
Per QLogic release notes, after 4.0.25 f/w the WWPN comes with the
PLOGI/PDISC/ADISC and LOGO ELS codes in the immediate notify structure.
This makes initiator WWN maintenance *way* easier.

+ The 24XX code in isp_target_start_ctio was setting the wrong values
to set SENSE LENGTH VALID for the FCP RSPNS IU.
+ Amusingly enough, this apparently didn't matter. In fact, once sense
data was being put into the ct7_entry_t there was *still* a problem
and REQUEST SENSE was being sent by the Linux initiator.
+ What *was* happening is that the 24XX requries the response data to
be 32 bit swapped. This is not obvious from the chip documents.

This is SCST driver for ISP Qlogic chipsets commonly used in many SCSI and FC
host bus adapters. Supported chipset are listed in README file, incomplete
list of supported HBA's is in doc/Hardware.txt .
It is based on Matthew Jacob's multiplatform driver for ISP chipsets,
which can be download from ftp://ftp.feral.com/pub/isp/isp_dist.tgz
