When toggle_irq is called for PCI devices to disable device interrupts
it used tasklet_disable to wait for a possibly running tasklet to finish.
However, on SMP systems the tasklet might still be scheduled on another CPU.
Instead, use tasklet_kill to ensure that all scheduled tasklets are finished
before returning from toggle_irq.

Furthermore, it was possible that a tasklet reenabled its interrupt even
though interrupts have been disabled already. Fix this by checking the
DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts
during tasklet processing.

While at it also enable/kill the TBTT and PRETBTT tasklets in the
toggle_irq callback and only use tasklet_kill in stop_queue to wait
for a currently scheduled beacon update before returning.

Let us enable/disable interrupts based on reference count.
By doing this we can ensure that interrupts are never be
enabled in the middle of tasklet processing. Instead of
addressing corner cases like "ath9k: avoid enabling interrupts
while processing rx", this approach handles it in generic manner.

At preset set_interrupt also enables interrupt after changing
mask. This is not necessary in all cases and also sometime it
breaks the assumption that interrupt was disabled. So let us
enable the interrupt explicity if it was disabled earlier.
This could also avoid unnecessary register ops and also helps
the follow up patch to have global ref count for interrupts ops.

Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

Modify the driver so that it does not function when the interface is
down, in preparation for runtime power management.

No commands can be run while the interface is down, so the ndo_dev_stop
routine now directly does all necessary work (including asking the device
to disconnect from the network and disabling multicast functionality)
directly.

power_save and power_restore hooks are added meaning that card drivers
can take steps to turn the device off when the interface is down.

The MAC address can now only be changed when all interfaces are down;
the new address will be programmed when an interface gets brought up.
This matches mac80211 behaviour.

Also, some small cleanups/simplifications were made in the surrounding
device handling logic.

Sometimes, the network manager is failing to connect to the AP due
to the below kernel crash message. The reason behind this,
after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.

The host driver resets all states (including cfg80211 state machine)
when it receives disconnect event from the chip. But, still the host
driver reports the next received connect event to cfg80211, at that time
cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.

Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211
