99e4638821 'sin' is never used after assignment. Looking at the context, it seems
that it belongs the commented out section of code so make it part of that
section.

921af50782 Always execute REPORT LUNS and REQUEST SENSE commands locally.
REPORT LUNS command is more related to target rather then specific LUN.
This node may be primary for LUNs for some reason unknown to another,
and command forwarded to another node won't be able to report them.

REQUEST SENSE is related to LUN, but in our implementation it reports
only UAs and CAs, that are stored locally rather then on primary node.

8729f5ec0e Improve and expand sesutil(8)
- 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

1508ab98e5 META_MODE: No need to fix the link in this case.
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.

df884b5ca7 META_MODE: Avoid command changing in 2nd build.
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.

75a3108e13 Relax serseq option operation for reads.
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.

0d3d0cc358 Kernel part of reroot support - a way to change rootfs without reboot.
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().

0510aedcd5 Do not execute exception handlers with disabled interrupts.
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.

23386fa4b6 Add in a temporary (hah!) workaround for net80211 scanning versus NIC
requirements.

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.

1f3a8d1129 Add an external facing function to manually set the RX A-MPDU parameters

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.

4b9d9eee03 Add initial 11n support to if_rsu.
* 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.
