- Return an error if no matching device is found when the locate command is run
- Enhance the locate command to be able to address drive bays with no disk, or where the SES controller has not made the mapping to the device name
- Added the fault command, similar to locate, but a different SES property. On some of my controllers locate blinks the activity light, others the fault light. The fault command keeps the fault light on constant.
- Improve the usage() output and use it everywhere
- Added the map command, displays all elements connected to each (or the specified) ses(4) controller
- Added the status command, returns the overall status of the ses(4) controller

* Since new extries are now allocated explicitly, fill in
all the necessary fields for lle _before_ attaching it to the table.
* Remove ND6_LLINFO_INCOMPLETE check which was unused even in
first KAME merge (r53541).
* After that, the only new state that function can set, was
ND6_LLINFO_STALE. Given everything above, simplify logic besides
do_update and is_newentry.
* Fix nd_resolve() comment.
The exists(${DESTDIR}...) check runs with DESTDIR being blank. When the
target runs it does have DESTDIR=${STAGE_OBJTOP} via bsd.sys.mk. This
results in the first execution warning that the symlink is missing. The
second run does run fine. However, this chflags is not needed at all
for META_MODE/STAGING since we never had this path being a schg file
while using META_MODE.

If the command to be ran changes then a rebuild is caused. Checking
exists(${DESTDIR}...) from make results in this on the 2nd and
possibly subsequent builds due to staging during build. Avoid this
by always running the existence check in the make sh command.

The BSD.usr.dist mtree always creates /usr/lib/dtrace so there is no
need to check if it exists.
The FILES mechanism already supports LIBRARIES_ONLY.

Previously, with serseq enabled, next command was unblocked only after
previous completed. With this change, for read operations, next command
is unblocked as soon as last media read completed. This is important
for frontends that actually wait for data move completion (like camtgt),
or when data are moved through the HA link, or especially when both.
Note that the mountlist manipulations are somewhat fragile, and not very
pretty. The reason for this is to avoid changing vfs_mountroot(), which
is (obviously) rather mission-critical, but not very well documented,
and thus hard to test properly. It might be possible to rework it to use
its own simple root mount mechanism instead of vfs_mountroot().

We should not call vm_fault(), or send a signal, with interrupts
disabled. MI kernel code is not prepared for such environment, not to
mention that this increases system latency, since code appears to be
executing as being under spinlock.
The FAR register for data aborts is read before the interrupts are
enabled, to avoid its corruption due to nested exception or context
switch.
Add asserts, similar to the checks done by other architectures, about
not taking page faults in non-sleepable contexts, rather than die with
late and somewhat confusing witness diagnostic.

Don't start the opmode and join path until a pending survey is finished.
This seems to reliably fix things.
Ideally I'd just finish off the net80211 pluggable scan stuff and implement
the methods here so if_rsu can just drive the scan machinery.
However, that's a .. later thing.
Whilst here, remove the getbuf debugging; it's okay to run out of transmit
buffers under load; it however isn't okay to not be able to send commands.
I'll fix that later.
for re-ordering.
Devices like if_rsu don't pass through action/management frames but do send
firmware commands to inform us of things. One of those notifications is
the RX A-MPDU negotiated parameters.
* Add a tunable to enable 11n if it's available, so to not anger people
who upgrade.
kenv hw.usb.rsu.enable_11n=1 before inserting the device.
* Add initial 11n htconfig bits;
* Enable 40MHz mode if it's available;
* Add 11n channels;
* Set 11n bits in the firmware.
It works for RX; I haven't tested TX aggregation just yet.
However the firmware doesn't do RX re-ordering, so I have to tie it into
the net80211 A-MPDU RX reorder path before I flip this on by default.
I've verified that I'm indeed actually seeing MCS 0->7 rates being received.
I haven't dug into whether it's actually transmitting 11n rates; I'll dig into
that later.
with a reference count of zero can't possibly be mapped, so there is never a
need for vm_page_set_invalid() to call pmap_remove_all() on them.

Also note that these env-only vars can be specified on the command line.
This fixes the dependent options that are env-only (such as WITH_META_MODE
and WITH_AUTO_OBJ) to properly display their dependencies.

No functional change.
While I'm there, raise WARNS to 2.
