* Right now the delay is hard coded at 10uS. This is a bit long when doing lots
of periodic i2c transactions. So create a 'udelay' parameter and initialise it
to 10. This can be tuned later.

performance issues.
* Access to the GPIO bus is already locked by requesting
and releasing the bus - thus the lock isn't really needed
for each GPIO pin change.
* Don't lock and unlock the GPIO bus for -each- i2c access -
the i2c bus code is already doing this by calling the upper
layer callback to request/release the bus. This thus locks
the bus for the entirety of the transaction.
TODO:
* Further verify that everything is correctly requesting/
releasing the GPIO bus.
* Look at how to lock the GPIO pin configuration stuff,
potentially by locking/unlocking the bus at the gpiobus
layer.
Fix the TCP header size calculation such that makes TSO engine
cache all header(ethernet/IP/TCP) bytes to its internal buffer.
While here, remove extra pull up for TCP payload. Unlike some
em(4) controllers, fxp(4) does not require such work around for
TSO.
The two limitations are ethernet/IP/TCP header size should be less
than or equal to the size of controller's internal buffer(80 bytes)
and these header information should be found in the first fragment
of a TSO frame.
of the rx_ring to bus_dmamap_sync(9). Given that netmap code tries to
obtain the bus addresses of netmap buffers via vtophys(9) instead of using
bus_dma(9) it currently has zero chance of actually working on sparc64
though (and for that matter f.e. also not with MACs limited to 32-bit DMA
on x86 machines with more than 4GB of RAM).
- put underlying keyboard(s) into the polling mode for the whole

- ditto for setting K_XLATE mode and enabling a disabled keyboard

At the moment grab and ungrab methods of all console drivers are no-ops.
Current intended meaning of the calls is that the kernel takes control of
console input. In the future the semantics may be extended to mean that
the calling thread takes full ownership of the console (e.g. console
output from other threads could be suspended).

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.

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.

As C1X is close to being released, there is no need to wrap around a
