The function_set/function_clear bits allow for individual GPIO pins to either

attached this way.
The AR5212 based NICs have a variety of RF frontends, so there's a linker set
which the AR5212 attach routine calls. The same framework is used for the
AR5416 and later but as there's a fixed RF frontend for each 11n NIC, it
is just directly attached.
However in the case of compiling a cut down HAL (eg _just_ AR9130 WMAC support),
the linker set ends up being empty and this causes the compile to fail.
So this is just a workaround for that - it means those users who wish an 11n
only HAL can compile the 11n chipsets and RF frontend they need, and just
"ath_ar5212" for the AR5212/AR5416 common code, and it'll just work.

* Call it before sending probe responses, so the ACL code has the
chance to reject sending them.
* Pass the whole frame to the ACL code now, rather than just the
destination MAC - that way the ACL module can look at the frame
contents to determine what the response should be.
This is part of some uncommitted work to support band steering.

The reverse direction of a pipe is lazily allocated on the first write in
that direction (because pipes are usually used in one direction only). A
special case is needed to ensure the pipe appears writable before the first
write because there are 0 bytes of pending data in 0 bytes of buffer space
at that point, leaving 0 bytes of data that can be written with the normal
code.
Note that the first write returns [ENOMEM] if kern.ipc.maxpipekva is
exceeded and does not block or return [EAGAIN], so selecting true for write
is correct even in that case.

provides a convenient way for creating shared memory buffers between
userland and the kernel without requiring custom character devices.
This removes the obfuscations mentioned in ext2_readwrite and
places the clustering funtion in a location similar to other
UFS-based implementations.
No performance or functional changeses are expected from
this move.

from the dispatcher would also acquire bind lock in read mode, which
is the supported operation. plt is explicitely designed to allow safe
multithreaded updates, so the shared lock do not cause problems.
The error in r228435 is that it allows read lock acquisition after the
write lock for the bind block. If we dlopened the shared object that
contains IRELATIVE or jump slot which target is STT_GNU_IFUNC, then
possible recursive plt resolve from the dispatcher would cause it.
Postpone the resolution for irelative/ifunc right before initializers
are called, and drop bind lock around calls to dispatcher. Use
initlist to iterate over the objects instead of the ->next, due to
drop of the bind lock in iteration.
For i386/reloc.c:reloc_iresolve(), fix calculation of the dispatch

- Add _Alignas(). Unfortunately this macro is only partially functional.
The C1X standard will allow both an integer and a type name to be
passed to this macro, while this macro only allows an integer. To be
portable, one must use _Alignas(_Alignof(double)) to use type names.
- Don't do _Static_assert() when __COUNTER__ is not supported. We'd
better keep this implementation robust and allow it to be used in
header files, without mysteriously breaking older compilers.

o Add check for actually resolved speed in miibus_statchg callback
instead of blindly reprogramming BCE_EMAC_MODE register. The
callback may be called multiple times(e.g. link UP, link
transition, auto-negotiate complete etc) while auto-negotiation
is in progress. All unresolved link state changes are ignored
now and setting BCE_EMAC_MODE after link establishment is done
once.
o bce(4) is careful enough not to drive MII_TICK if driver got a
valid link. To detect lost link, bce(4) relied on link state
change interrupt and if driver see the interrupt, it forced to
drive MII_TICK by calling bce_tick() in interrupt handler.
Because bce(4) generates multiple link state change interrupts
while auto-negotiation is in progress, bce_tick() would be
called multiple times and this resulted in generating multiple
link UP/DOWN messages.
With this change, bce_tick() is not called in interrupt handler
anymore such that miibus_statchg callback handles link state
changes with consistent manner.

__COUNTER__ allows one to obtain incrementing (read: unique) numbers
from the C preprocesor. This is useful when implementing things like a
robust implementation of CTASSERT(), which currently fails when using
it more than once on a single line of code. Probably not likely to cause
any breakage, but still.
__COUNTER__ was also added to GCC 4.3, but since that implementation is
GPLv3 licensed, I took the liberty of implementing it without looking at
any upstream sources. Therefore, this version is licensed under the same
license as the rest of the code; GPLv2.
