251c177f88 wl12xx: replace dummy_join with ROC/CROC commands
The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:

1. Allow tx/rx from the device role.

In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.

Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.

2. Keeping the antenna for a specific link.

We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).

During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.

Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.

Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.

The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control
the ROC during connection.

154037d168 wl12xx: change max/default template size
The max template size was increased in the new fw.
However, we should use the max size only when needed, as it
consumes some of the chip's memory.

Thus, by default initialize the templates to the default size.
Initialize to the maximum size only when required.

Use WL1271_CMD_TEMPL_DFLT_SIZE instead of some of the
predefined structs, as some of them didn't account
for additional IEs that might be added to the template.

Currently, we don't really support multi-role, as

f3d4505de5 ath9k: remove eeprom txgain override for minor version < 19
ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the
minor version is not 19 or above with a value of 0.
ar9002_hw_init_mode_gain_regs() relies on this information to
determine whether this is a high power wifi card or not. The override
caused the driver to always use the 'normal' power tables even for
high power devices if their minor version was not high enough. Thus
leading to reduced power output.

This isn't needed for the AR9285; the check originated with the
AR9280 setup code which requires the EEPROM version check.

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.

886e14b65a rtlwifi: Eliminate raw reads and writes from PCIe portion
The PCIe driver used raw reads and writes on the PCIe hardware.
As all of these are only affecting the configuration space, all of
then can be converted to pci_{read,write}_config_XX calls.

e8fe733684 ath9k: Use atomic reference count for interrupt ops
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.

a844adfd7b ath9k_hw: Fix incorrect spur_freq_sd for AR9003
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.
