only allows basic username/password config, and does not provide the
ability to set any of the other WPA options. Regardless, this is
generally sufficient to associate.
Perhaps in the future this could allow full configuring (e.g. being able
to set "anonymous identity", and perhaps some of the more obscure WPA
options), though perhaps that will better belong in bsdconfig when that
grows wlan config ability.

New algorithm does not create additional lock congestion, while some races
it includes should not be a problem. Those races may keep requests in DRC
cache for some more time by returning ACK position smaller then actual,
but it still should be able to drop thems when proper ACK finally read.
Races of the original algorithm based on TCP seq number were worse because
they happened when reply sequence number were recorded. After that even
correctly read ACKs could not clean DRC sometimes.
* Set errno to EAFNOSUPPORT if an address is provided which is neither
AF_INET nor AF_INET6.
* Don't modify the arguments.
* Don't smash the stack when provided with a non-zero port.
* Handle the case correctly where the first address provided is
an IPv6 address.

- Compile the tests with .t suffix, so prove can use them directly.
- The CHECKX() macro should increment ntest just like the CHECK() macro.
- For consistency remove # from the pwd.t output.

searching. If you didn't configure a timer capture pin you'd get a data
abort as it wandered into the weeds, now you get a nice warning message
about your config, as originally intended.
guest disables the HPET.
The HPET timer interrupt is triggered from the callout handler associated with
the timer. It is possible for the callout handler to be delayed before it gets
a chance to execute. If the guest disables the HPET during this window then the
handler never gets a chance to execute and the timer interrupt is lost.
This is now fixed by injecting a timer interrupt into the guest if the callout
time is detected to be in the past when the HPET is disabled.
the LED specification was just misplaced). The rather odd memory mappings
that were in place used an undocumented attribute value (0x0f) that caused
problems with the system.

Callers do that already and additional check races with process
decreasing limits and can result in not growing the table at all, which
is currently not handled.

- Introduce additional hash to group requests by hash of sockref. This
allows to process TCP acknowledgements without looping though all the cache,
and as result allows to do it every time.
- Indroduce additional callbacks to notify application layer about sockets
disconnection. Without this last few requests processed just before socket
disconnection never processed their ACKs and stuck in cache for many hours.
- Implement transport-specific method for tracking reply acknowledgements.
New implementation does not cross multiple stack layers to get the data and
does not have race conditions that previously made some requests stuck
in cache. This could be done more efficiently at sockbuf layer, but that
would broke some KBIs, while I don't know other consumers for it aside NFS.
- Instead of traversing all DRC twice per request, run cleaning only once
per request, and except in some conditions traverse only single hash slot
at a time.
Together this limits NFS DRC growth only to situations of real connectivity
problems. If network is working well, and so all replies are acknowledged,
cache remains almost empty even after hours of heavy load. Without this
change on the same test cache was growing to many thousand requests even
with perfectly working local network.
As another result this reduces CPU time spent on the DRC handling during
SPEC NFS benchmark from about 10% to 0.5%.

LPC devices. Among other things, the LPC serial ports now appear as
ACPI devices.
- Move the info for the top-level PCI bus into the PCI emulation code and
add ResourceProducer entries for the memory ranges decoded by the bus
for memory BARs.
- Add a framework to allow each PCI emulation driver to optionally write
an entry into the DSDT under the \_SB_.PCI0 namespace. The LPC driver
uses this to write a node for the LPC bus (\_SB_.PCI0.ISA).
- Add a linker set to allow any LPC devices to write entries into the
DSDT below the LPC node.
- Move the existing DSDT block for the RTC to the RTC driver.
- Add DSDT nodes for the AT PIC, the 8254 ISA timer, and the LPC UART
devices.
- Add a "SuperIO" device under the LPC node to claim "system resources"
aling with a linker set to allow various drivers to add IO or memory
ranges that should be claimed as a system resource.
- Add system resource entries for the extended RTC IO range, the registers
used for ACPI power management, the ELCR, PCI interrupt routing register,
and post data register.
- Add various helper routines for generating DSDT entries.

Unfortunately this causes ICE on powerpc and sparc64.
Reducing these differences against upstream is not important
anymore so hopefully I have finished breaking the compiler
occasionally.
Thus we can use IF_AFDATA_RLOCK() instead of IF_AFDATA_LOCK() when doing
lla_lookup() without LLE_CREATE flag.

When we encounter an I/O error on a piece of metadata while deleting
a file system or zvol, we don't update the bptree_entry_phys_t's
bookmark. This would lead to double free of bp's which will lead to
space map corruption.
Instead of tolerating and allowing the corruption, panic immediately.
See Illumos #4390 for more details.
