When user space SME/MLME (e.g., hostapd) is not used in AP mode, the
IEs from the (Re)Association Request frame that was processed in
firmware need to be made available for user space (e.g., RSN IE for
hostapd). Allow this to be done with cfg80211_new_sta().

Drivers that support frame transmission with mgmt_tx() may not support
driver-based offchannel TX. Use mgmt_tx_cancel_wait instead of mgmt_tx
when figuring out whether to indicate support for this with
NL80211_ATTR_OFFCHANNEL_TX_OK.

RX_FLAG_HT must be included when reporting MCS rates. Without
this, mac80211 ended up dropping any frame sent at MCS index 12
or higher and that resulted in oddly random looking errors in
mac80211_hwsim tests.

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.

Spur frequency was incorrectly computed with 10Mhz offset
which could cause the filter would not notch out the spur
and also this could improve rx sensitivity in HT40.

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.

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.

Some drivers (ath9k for example) are using skb->protocol to treat EAPOL
frames somehow special (disallow aggregation for example).
When running in AP mode hostapd injects the EAPOL frames through a
monitor interface and thus skb->protocol isn't set at all. Hence, if the
injected frame is a data frame and carries a rfc1042 headaer update the
skb->protocol field accordingly.
