that was implemented for the NDIS-subsystem watchdog. This
implementation is similar to what numerous other drivers use

- Add a mutex to the softc and use it to protect the softc and device.
- Setup the interrupt handler in the common code instead of in each front
end and do it after ether_ifattach().
- Use ie_stop() and ieinit_locked() in iereset() rather than frobbing IFF_UP
and invoking ieioctl().
- Use DELAY() to implement a spin loop on a register with a timeout rather
than scheduling a timeout and then doing a tight spin on the register.
In the non-MPSAFE case this would never have worked because the spinning
code held Giant and the timeout routine would have been blocked on Giant
forever. The same approach would not worke in the MPSAFE case either for
the same reason, hence use a loop around DELAY().
- Clear IFF_DRV_(RUNNING|OACTIVE) in ie_stop() rather than in callers.
- Call ieinit_locked() directly rather than ieioctl(!) from ie_mc_reset().
- Don't leak the rx frame buffer on detach.

variations from normal 16x50 behaviour however is the the use of a normally
unused bit of IER to control RX timeout interrupts independently of the
generally used RXRDY bit. If this bit is not enabled, we only ever get
interrupts when the FIFO is full, never before. This is not very useful when
the UART is being used as a console.
In order to support this without causing potential problems on more "normal"
16x50 variants, this change introduces two hints for the uart device, ier_mask
and ier_rxbits. These can be used to override which bits get set and cleared
when we're enabling and disabling RX interrupts.

Even though we got rid of device major numbers some time ago, device
drivers still need to provide unique device minor numbers to make_dev().
These numbers are only used inside the kernel. They are not related to
device major and minor numbers which are visible in devfs. These are
actually based on the inode number of the device.
It would eventually be nice to remove minor numbers entirely, but we
don't want to be too agressive here.
Because the 8-15 bits of the device number field (si_drv0) are still
reserved for the major number, there is no 1:1 mapping of the device
minor and unit numbers. Because this is now unused, remove the
restrictions on these numbers.
The MAXMAJOR definition was actually used for two purposes. It was used
to convert both the userspace and kernelspace device numbers to their
major/minor pair, which is why it is now named UMINORMASK.
minor2unit() and unit2minor() have now become useless. Both minor() and
dev2unit() now serve the same purpose. We should eventually remove some
of them, at least turning them into macro's. If devfs would become
completely minor number unaware, we could consider using si_drv0 directly,
just like si_drv1 and si_drv2.

o do not put the chip into full sleep in ath_stop as it gains
nothing and causes many parts to hang in ath_detach because we
may touch the chip during vap teardown; this may also fix issues
with unloading the module
o add a note in ath_detach to explain ath_hal_detach puts the
chip in low power mode; this is useful to know as it means
unloading the module will place a pci device in the lowest
possible power state
o leave an #ifdef notyet marker for powering down the chip when
a device is marked down; we can't do that until we handle all
the ways the driver may be entered and touch the chip
o fix resume by reloading the h/w key cache as it's been clobbered
(for pci) by the socket being powered off; for station mode we
directly stop+init the chip and then simulate a beacon miss to
get the upper layers sync'd up; for other configs we must brute
force stop+start the vaps so they go through the state machine
on amd64. Note the only difference is the iovec32 part so I use the
native structure for everything else.
Also I plan to MFC all the changes in -current to 7-stable and 6-stable

gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
supports all hardware features except RSS and multiple Tx/Rx queue.
In these days most ethernet controller vendors take a ply of
concealing hardware detailes from open source developers. As
contrasted with these vendors JMicron provided all necessary
information needed to write a stable driver during driver writing
and answered many questions I had. They even helped fixing driver
bugs with protocol analyzer. Many thanks to JMicron for their
support of FreeBSD.

Resolve this issue with what we do for other NICs by
splitting the iwn_start procedure into two parts,
iwn_start() do the locking, and iwn_start_locked()
assumes that the mutex is being held. This resolves

seem to require careful tuned parameters to get best
performance. Datasheet for L1 is not available to open source
driver writers so age(4) focus on stability and correctness of
basic Tx/Rx operation. ATM the performance of age(4) is far from
optimal which in turn means there are mis-programmed registers or
incorrectly configured registers.
Currently age(4) supports all known hardware assistance including

- TCP Segmentation Offload.
- Hardware VLAN tag insertion/stripping.

(AR81xx) from Atheros. These are not supported by age(4) and
requires a seperate driver. Big thanks to all people who reported
feedback or tested patches.
