Fix Fibre Channel Command Reference Number handling in the isp(4) driver.
The Command Reference Number is used for precise delivery of commands, and is part of the FC-Tape functionality set. (This is only enabled for devices that support precise delivery of commands.) It is an 8-bit unsigned number that increments from 1 to 255. The commands sent by the initiator must be processed by the target in CRN order if the CRN is non-zero.
There are certain scenarios where the Command Reference Number sequence needs to be reset. When the target is power cycled, for instance, the initiator needs to reset the CRN to 1. The initiator will know this because it will see a LIP (when directly connected) or get a logout/login event (when connected to a switch).
The isp(4) driver was not resetting the CRN when a target went away and came back. When it saw the target again after a power cycle, it would continue the CRN sequence where it left off. The target would ignore the command because the CRN sequence is supposed to be reset to 1 after a power cycle or other similar event.
The symptom that the user would see is that there would be lots of aborted INQUIRY commands after a tape library was power cycled, and the library would fail to probe. The INQUIRY commands were being ignored by the tape drive due to the CRN issue mentioned above.
isp_freebsd.c: Add a new function, isp_fcp_reset_crn(). This will reset all of the CRNs for a given port, or the CRNs for all LUNs on a target.
Reset the CRNs for all targets on a port when we get a LIP, loop reset, or loop down event.
Reset the CRN for a particular target when it arrives, is changed or departs. This is less precise behavior than the clearing behavior specified in the FCP-4 spec (which says that it should be reset for PRLI, PRLO, PLOGI and LOGO), but this is the level of information we have here. If this is insufficient, then we will need to add more precise notification from the lower level isp(4) code.
isp_freebsd.h: Add a prototype for isp_fcp_reset_crn().

Fix a kernel panic when unloading isp(4).
In the current implementation, the isp_kthread() threads never exit.
The target threads do have an exit mode from isp_attach(), but it is not invoked from isp_detach().
Ensure isp_detach() notifies threads started for each channel, such that they exit before their parent device softc detaches, and thus before the module does. Otherwise, a page fault panic occurs later in:
sysctl_kern_proc sysctl_out_proc kern_proc_out fill_kinfo_proc fill_kinfo_thread strlcpy(kp->ki_wmesg, td->td_wmesg, sizeof(kp->ki_wmesg));
For isp_kthread() (and isp(4) target threads), td->td_wmesg references now-unmapped memory after the module has been unloaded. These threads are typically msleep()ing at the time of unload, but they could also attempt to execute now-unmapped code segments.

Optimize isp(4) to reduce CPU usage, especially in target mode: - Remove two excessive and slow register reads from isp_intr(). Instead of rereading value every time, assume that registers contain what we have written there. - Avoid sequential search through 4096 array elements when looking for command tag. Use hash of lists to store active tags separately from free ones and so greatly speedup the searches.

More rototilling with target mode in an attemp to get multiple CCB at a time outstanding reliable. It's not there yet, but this is the direction to go in so might as well commit. So far, multiple at a time CCBs work (see ISP_INTERNAL_TARGET test mode), but it fails if there are more downstream than the SIM wants to handle and SRR is sort of confused when this happens, plus it is not entirely quite clear what one does if a CCB/CTIO fails and you have more in flight (that don't fail, say) and more queued up at the SIM level that haven't been started yet.
Some of this is driven because there apparently is no flow control to requeue XPT_CONTINUE_IO requests like there are for XPT_SCSI_IO requests. It is also more driven in that the few target mode periph drivers there are are not really set up for handling pushback- heck most of them don't even check for errors (and what would they really do with them anyway? It's the initiator's problem, really....).
The data transfer arithmetic has been worked over again to handle multiple outstanding commands, so you have a notion of what's been moved already as well as what's currently in flight. It turns that this led to uncovering a REPORT_LUNS bug in the ISP_INTERNAL_TARGET code which was sending back 24 bytes of rpl data instead of the specified 16. What happened furthermore here is that sending back 16 bytes and reporting an overrun of 8 bytes made the initiator (running FC-Tape aware f/w) mad enough to request, and keep requesting, another FCP response (I guess it didn't like the answer so kept asking for it again).

----------- MISC CHANGES
Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best.
Clean up the lower level lun enable code to be a bit more sensible.
Fix a botch in isp_endcmd which was messing up the sense data.
Fix notify ack for SRR to use a sensible error code in the case of a reject.
Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA
In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes.
Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly.
On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver.
This is supported on 23XX, 24XX and 25XX cards.
This is also preparation for doing >16 byte CDBs.
----------- FC TAPE
Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards.
On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN.
In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it.
On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so.
If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame.
If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit.
However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well.
At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Prepare for FC-Tape support. This involved doing a lot of little cleanups and crosschecks against firmware documentation. We now check and report FC firmware attributes and at least are now prepared for the upper 48 bits of f/w attributes (which are probably for the 8100 or later cards). This involed changing how inbits and outbits are calculated for varios commands, hopefully clearer and cleaner. This also caused me to clean up the actual mailbox register usage. Finally, we are now unconditionally using a CRN for initiator mode.
A longstanding issue with the 2400/2500 is that they do *not* support a "Prefer PTP followed by loop", which explains why enabling that caused the f/w to crash.
A slightly more invasive change is to let the firmware load entirely drive whether multi_id support is enabled or not.

If we default to role 'none', this causes a reset of the 24XX f/w which then causes initiators to wake up and notice when we come online.
