a new firmware command.
NVMe controllers may support up to 7 firmware slots for storing of
different firmware revisions. This new firmware command supports
firmware replacement (i.e. firmware download) with or without immediate
activation, or activation of a previously stored firmware image. It
also supports selection of the firmware slot during replacement
operations, using IDENTIFY information from the controller to
check that the specified slot is valid.
Newly activated firmware does not take effect until the new controller
reset, either via a reboot or separate 'nvmecontrol reset' command to the
same controller.

Also allow admin commands to transfer up to this maximum I/O size, rather
than the artificial limit previously imposed. The larger I/O size is very
beneficial for upcoming firmware download support. This has the added
benefit of simplifying the code since both admin and I/O commands now use
the same maximum I/O size.

Also move helper function prototypes to the end of the header file, after

by treating it as UDMA.
This fixes a problem introduced in r249933/r249939, where CAM sends
ATA_DSM_TRIM to SATA devices using ATA_PASSTHROUGH_16. scsi_ata_trim()
sets protocol as DMA (not UDMA) which is for multi-word DMA, even
though no such mode is selected for the device. isci(4) would fail
these commands which is the correct behavior but not consistent with
other HBAs, namely LSI's.
smh@ did some further testing on an LSI controller, which rejected
ATA_PASSTHROUGH_16 commands with mode=UDMA_OUT, even though only
a UDMA mode was selected on the device. So this precludes adding
any kind of mode detection in CAM to determine which mode to use on
a per-device basis.

support cache flush and write barrier commands.
sys/dev/xen/blkfront/block.h:
Add per-command flag that specifies that the I/O queue must
be frozen after this command is dispatched. This is used
to implement "single-stepping".
Remove the unused per-command flag that indicates a polled
command.
Add block device instance flags to record backend features.
Add a block device instance flag to indicate the I/O queue
is frozen until all outstanding I/O completes.
Enhance the queue API to allow the number of elements in a
queue to be interrogated.
Prefer "inline" to "__inline".
sys/dev/xen/blkfront/blkfront.c:
Formalize queue freeze semantics by adding methods for both
global and command-associated queue freezing.
Provide mechanism to freeze the I/O queue until all outstanding
I/O completes. Use this to implement barrier semantics
(BIO_ORDERED) when the backend does not support
BLKIF_OP_WRITE_BARRIER commands.
Implement BIO_FLUSH as either a BLKIF_OP_FLUSH_DISKCACHE
command or a 0 byte write barrier. Currently, all publicly
available backends perform a diskcache flush when processing
barrier commands, and this frontend behavior matches what
is done in Linux.
Simplify code by using new queue length API.
Report backend features during device attach and via sysctl.

The AHB code:
* hard coded the AR9130 device id;
* assumes a 4k flash calibration space.
This code now extends this:
* hint.ath.X.eepromsize now overrides the eeprom range, instead of 4k
* hint.ath.X.device_id and hint.ath.X.vendor_id can now be overridden.
Tested:
* AR9330 board (Carambola 2)
When building AR933x test images, I'd like to only build only the ar9300
HAL. To do this, it needs to supply an RF linker entry or it won't compile.
Tested:
* AR933x test builds
In BSD, fgetln() available in libc but in Illumos the Solaris port had to
include it internally. It also seems to have caused problems [1].
Aid portability by using getline() instead.

Not only this is a bit cleaner, it allows multiple instances of hostapd to be
running on the system host, useful for simultaneous dual-band WiFi.
This is similar to ifconfig_wlanX="WPA" but it uses /etc/hostapd-wlanX.conf.
Compatibility with hostapd_enable=YES/NO was kept.

- Call lock_init() first before setting any lock_object fields in
lock init routines. This way if the machine panics due to a duplicate
init the lock's original state is preserved.
- Somewhat similarly, don't decrement td_locks and td_slocks until after
an unlock operation has completed successfully.

- Add an rm_assert() supporting various lock assertions similar to other
locking primitives. Because rmlocks track readers the assertions are
always fully accurate unlike rw_assert() and sx_assert().
- Flesh out the lock class methods for rmlocks to support sleeping via
condvars and rm_sleep() (but only while holding write locks), rmlock
details in 'show lock' in DDB, and the lc_owner method used by
dtrace.
- Add an internal destroyed cookie so that API functions can assert
that an rmlock is not destroyed.
- Make use of rm_assert() to add various assertions to the API (e.g.
to assert locks are held when an unlock routine is called).
- Give RM_SLEEPABLE locks their own lock class and always use the
rmlock's own lock_object with WITNESS.
- Use THREAD_NO_SLEEPING() / THREAD_SLEEPING_OK() to disallow sleeping
while holding a read lock on an rmlock.

forced to 3 so that the output of this script is always displayed.
In fact, setting this flag is identical to setting
daily_status_security_output to an empty string. To make the logic
less confusing, change the behavior of daily_status_security_inline
such that it just forces daily_status_security_output to an empty
string and then applies the normal logic.

There are some systems reported, where PCI BAR(5), used for SATA registers
access, is present, but not functional. Attempt to use it brakes devices
detection logic. Try to detect those cases on attach by setting and testing
some bits in SControl register. If bits are unsettable, fallback to legacy
ATA without hot-plug detection, speed control/reporting, etc.
