b0aa0c6e1b timeout: handle zombie grandchildren
timeout previously collected only one child status with wait(2). If this
was one of the grandchildren timeout would return to sigsuspend and wait
until the timeout expired. Instead, loop for all children.

caa918bd3b Add ath_hal_setbeacontimers() to the AR9300 HAL.
This is a custom FreeBSD HAL method that is used by the TDMA code
to program the beacon timers directly without any guesswork/assumptions
by the HAL.

This brings up basic TDMA master/slave support on the AR9380 HAL,
however there are other issues preventing it from being stable.
(I'm seeing beacon interval instability, which may be due to
busy 2GHz air, but also may be due to some HAL configuration
issues with regards to ANI, or hardware timer programming, etc.)

Tested:

* AR9331 (Carambola2), STA, AP, adhoc and TDMA master mode.

09cc2762fa More tidy-ups on uninitialized scalar variable
As a followup to r278363, there is one more case where
stayopen can be accessed uninitialized, but even after
swapping arguments, access is possible in some other
cases so prevent it completely by initializing stayopen.

e291429c5b ulimit(3): Fix broken check.
The existing implementation had a broken comparison that could
overflow and return confusing values.  Replace this with a check
that avoids the overflow before it happens.

Consistently return a maximum value also on the case of negative
arguments since negative is considered an overflow and means
infinity for our current setrlimit().

New revamped version is credited to Bruce Evans.

6c176113bb Quirk based support of Chromebook keyboard found in Acer C720
This probably supports other devices based on SeaBIOS, which need
to be added to the smbios based quirks table.

The functionality has been ported from DragonFlyBSD and adapted
to FreeBSD's more general purpose environment.

Devices not covered by a quirk shouldn't be affected at all. Thanks
to jhb and kostikbel for reviewing the code.

It is safe to move the call to socantsendmore_locked() after

35a32b0476 Move the lock destruction/creation to earlier in the process - if
interrupts are enabled and the NIC is awake (think: loading a module)
then there's a not-quite-zero window where we'll get an interrupt
for the device before the attach method is called to finish setting
up the hardware.

Since I grab locks in ath_intr() to check various things, the locks
need to be ready much earlier.

06f874e1f9 Remove the reserved pin 11 from the HAL check.
The QCA9565 can have RFKILL on GPIO Pin 11, and thus we need to configure
it up correctly or the NIC may not function.

I'm not sure why the AR9382 can't use GPIO 8 / GPIO 11 ; it's likely
hooked up to some external LNA or filter.  The real solution is to
make it only block pin 8 / pin 11 for AR9382, but the AR9382 probes
like an AR9380.  Sigh.
