The existing logic wrapped programming nexttbtt at 65535 TU.
This is not good enough for the 11n chips, whose nexttbtt register
(GENERIC_TIMER_0) has an initial value from 0..2^31-1 TSF.
So converting the TU to TSF had the counter wrap at (65535 << 10) TSF.
Once this wrap occured, the nexttbtt value was very very low, much
lower than the current TSF value. At this point, the nexttbtt timer
would constantly fire, leading to the TX queue being constantly gated
open.. and when this occured, the sender was not correctly transmitting
in its slot but just able to continuously transmit. The master would
then delay transmitting its beacon until after the air became free
(which I guess would be after the burst interval, before the next burst
interval would quickly follow) and that big delta in master beacon TX
would start causing big swings in the slot timing adjustment.
With this change, the nexttbtt value is allowed to go all the way up
to the maximum value permissable by the 32 bit representation.
I haven't yet tested it to that point; I really should. The AR5212
HAL now filters out values above 65535 TU for the beacon configuration
(and the relevant legal values for SWBA, DBA and NEXTATIM) and the
AR5416 HAL just dutifully programs in what it should.
With this, TDMA is now useful on the 802.11n chips.
Tested:
* AR5416, AR9280 TDMA slave
* AR5413 TDMA slave
what the maximum legal values are.
The current beacon timer configuration from TDMA wraps things at
HAL_BEACON_PERIOD-1 TU. For the 11a chips this is fine, but for
the 11n chips it's not enough resolution. Since the 11a chips have a
limit on what's "valid", just enforce this so when I do write larger
values in, they get suitably wrapped before programming.
Tested:
* AR5413, TDMA slave
Todo:
* Run it for a (lot) longer on a clear channel, ensure that no strange
slippages occur.
* Re-validate this on STA configurations, just to be sure.
much all the union of all the kernel configuration files, including all
the CPU types, Marvell SOC types and at91 board types. Any device not
supported (read: does not compile) has been removed, which is a fairly
small set actually. As such, LINT gives us very good coverage without
having to build a zillion kernels.
expand to uncompilable code when the kernel configuration contains
"options DEBUG", such as it is for LINT. The toolchain is often a
better approach to figure this out, as it doesn't require one to
boot the kernel.
interfere with structure fields of the same name in drivers, like
the intr_disable function pointer in struct cphy_ops in cxgb(4).
Instead define intr_disable and intr_restore as inline functions.
With intr_disable() an inline function, the I32_bit and F32_bit
macros now need to be visible in MI code and given the rather
poor names, this is not at all good. Define ARM_CPSR_F32 and
ARM_CPSR_I32 and use that instead of F32_bit and I32_bit (resp)
for now.
When using libc++ headers on FreeBSD, in combination with -std=c++98,
-ansi or -std=c++03, the long long type is not supported. So in this
case, several functions and types, like lldiv_t, strtoll(), are not
declared.
This should make it possible to use the libc++ headers in c++98 mode.
Note: libc++ is originally designed as a c++0x or higher library, so you
should still take care when using it with c++98 or c++03.

fail or not. The mbuf pointer is no longer valid, so
can't be reused after.
Fix igb_mq_start() where mbuf pointer was used after
drbr_enqueue().
This eventually leads us to all invocations of
igb_mq_start_locked() called with third argument as NULL.
This allows us to simplify this function.
