Add an isp(4) tunable to default to ispfw(4) firmware.

ispfw(4) recently gained firmware for Qlogic 27XX and 28XX
FC controllers, and isp(4) now selects the newer of firmware in
flash or in ispfw(4) to load for those controllers.

This differs from the previous behavior (which remains for older
controllers), which was to always load the ispfw(4) firmware if it
is available.

This adds a loader tunable, hint.isp.N.fwload_force to default to
loading the ispfw(4) firmware, whether or not it is newer than the
firmware in flash. This allows the user to always use the known
firmware version included with the kernel.

Note that there is an existing fwload_disable tunable that tells
the driver to always load the firmware from flash and ignore
ispfw(4). If fwload_disable is set, fwload_force will be ignored.
So users with existing fwload_disable tunables will have the same
behavior.

If a user specifies both fwload_force and fwload_disable for the
same controller, the isp(4) driver prints a warning message,
and fwload_disable will be honored.

The user can see which firmware is active through the
dev.isp.N.fw_version* sysctl variables.

share/man/man4/isp.4:
Document the new loader tunable.

sys/dev/isp/isp.c:
In isp_load_risc_flash(), changet the decision logic to
also consider ISP_CFG_FWLOAD_ONLY. Load the flash firmware
and get the version, so the user knows what it is, but if
the user set fwload_force, honor that. If the user didn't
set fwload_force, the behavior remains to select the newer
firmware version.

sys/dev/isp/isp_pci.c:
Add a new fwload_force tunable. Print out a warning if the
user sets both fwload_disable and fwload_force.

sys/dev/isp/ispvar.h:
Add a new ISP_CFG_FWLOAD_FORCE configuration bit.

isp(4): Rework firmware handling/loading

Correctly identify the active firmware in flash on adapters with
primary and secondary firmware region in flash.
Correctly identify the active NVRAM on adapters with primary
and secondary NVRAM region in flash.

Loading ispfw(4) moved from isp_pci_attach() to isp_reset().
Drop the reference to ispfw(4) after using it so one can kldunload(8) it.
New isp_load_ram() function to load either ispfw(4) or flash firmware
into RISC's RAM.
New functions to read data from flash. The old ones will be removed later.
A bunch of new helper functions to identify and validate active flash
regions for firmware, auxiliary and NVRAM.
Overhaul ISP_FW_* macros and make use of it when comparing firmware
versions. We can handle firmware versions up to 255.255.255.

Firmware load priority slightly changed:
For 27xx and newer adapters:
- load ispfw(4) firmware
- request (active) flash firmware information
- compare version numbers of ispfw(4) and flash firmware
- load firmware with highest version into RISC's RAM
- if loading ispfw(4) is disabled or failed - load firmware from flash
- if everything else fails use MBOX_LOAD_FLASH_FIRMWARE as fallback

For 26xx and older adapters nothing changed:
- load ispfw(4) firmware and load it into RISC's RAM
- if loading ispfw(4) is disabled or failed use MBOX_EXEC_FIRMWARE
- for 26xx a preceding MBOX_LOAD_FLASH_FIRMWARE is used

New read only sysctl(8)'s:
dev.isp.N.fw_version_run: the firmware version actually running
dev.isp.N.fw_version_ispfw: the firmware version provided by ispfw(4)
dev.isp.N.fw_version_flash: the (active) firmware version in flash

While here:
- firmware attribute handling/parsing reworked
+ renamed defines from ISP2400_FW_ATTR_* to ISP_FW_ATTR_*
+ changed values to match new handling/parsing
+ added some more attributes
- enable FLT support on 26xx based adapters
- log level adjustments
- new function return status codes (some for now, some for later use)
- some minor style changes

Tested and approved to work on real hardware with:
- Qlogic ISP 2532 (QLogic QLE2560 8Gb FC Adapter)
- Qlogic ISP 2031 (QLogic QLE2662 16Gbit 2Port FC Adapter)
- Qlogic ISP 2722 (QLogic QLE2690 16Gb FC Adapter)
- Qlogic ISP 2812 (QLogic QLE2772 32Gbit 2Port FC Adapter)

Remove parallel SCSI and 1/2Gb FC support from isp(4).

This removes 288KB (36%) of the driver code and zillions of hacks and
workarounds, making single driver uniformly support several different
generations of hardware interfaces, not counting minor card variations.
After years of the hopeless fight, I don't think it worth to continue
support for hardware obsolete for 15-20 years. Instead much cleaner
now code should allow to move forward toward better locking, multiple
queues and other cool features.

All the remaining Qlogic cards starting from 4Gb 24xx to 32Gb 27xx use
the same hardware/firmware interface with minor incremental improvements,
so it seems to be a good new starting point. Except one PCI-X model all
all of them are PCIe and so still usable in modern systems.

Switch fabric scans from GID_FT to GID_PT+GFF_ID/GFT_ID.

Instead of using GID_FT SNS request to get list of registered FCP ports,
use GID_PT to get list of all Nx_Ports, and then use GFF_ID and/or GFT_ID
requests to find whether they are FCP and target capable.

The problem with old approach is that GID_FT does not report ports without
FC-4 type registered. In particular it was impossible to boot OS from
FreeBSD FC target using QLogic FC BIOS, since one does not register FC-4
type even on new cards and so ignored by old code as incompatible.

As a side bonus this allows initiator to skip pointless logins to other
initiators by fetching that information from SNS instead.

In case some switches do not implement GFF_ID/GFT_ID correctly, add sysctls
to disable that functionality. I handled broken GFF_ID of my Brocade 200E,
but there may be other switches with different bugs.

Linux also uses GID_PT, but GFF_ID is disabled by default there, and GFT_ID
is not supported.

Turn on FC-Tape by default in the isp(4) driver.

FC-Tape provides additional link level error recovery, and is
highly recommended for tape devices. It will only be turned on for
a given target if the target supports it.

Without this setting, we default to whatever FC-Tape setting is in
NVRAM on the card.

This can be overridden by setting the following loader tunable, for
example for isp0:

hint.isp.0.nofctape=1

sys/conf/options:
Add a new kernel config option, ISP_FCTAPE_OFF, that
defaults the FC-Tape configuration to off.

sys/dev/isp/isp_pci.c:
If ISP_FCTAPE_OFF is defined, turn off FC-Tape. Otherwise,
turn it on if the card supports it.

share/man/man4/isp.4:
Add a description of FC-Tape to the isp(4) man page.

Add descriptions of the fctape and nofctape options, as well as the
ISP_FCTAPE_OFF kernel configuration option.

Add the ispfw module and kernel drivers to the suggested
configurations at the top of the man page so that users are less
likely to leave it out. The driver works well with the included
firmware, but may not work at all with whatever firmware the user
has flashed on their card.
