Felix Fietkau 319e7bd96a ath9k_htc: accept 1.x firmware newer than 1.3
Since the firmware has been open sourced, the minor version has been
bumped to 1.4 and the API/ABI will stay compatible across further 1.x
releases.

Luis R. Rodriguez 0c0280bd0b wireless: make the reg_notifier() void
The reg_notifier()'s return value need not be checked
as it is only supposed to do post regulatory work and
that should never fail. Any behaviour to regulatory
that needs to be considered before cfg80211 does work
to a driver should be specified by using the already
existing flags, the reg_notifier() just does post
processing should it find it needs to.

Also make lbs_reg_notifier static.

Johannes Berg 81ddbb5c11 mac80211: don't always advertise remain-on-channel
Not all devices are really capable of implementing
remain-on-channel, even if it is implemented in SW,
as they can't necessarily deal with channel changes
while associated.

Remove the WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL and add
it only if either the driver has remain_on_channel
implemented in the driver/device.

Also add it to all drivers that advertise P2P right
now since those definitely have to have it working.

Felix Fietkau 8a30930563 ath9k_hw: make bluetooth coexistence support optional at compile time
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.

This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.

On MIPS this reduces the total size for the modules by about 20k.

This reverts commit 0ce3bcfc84.

Event though with the above commit we obtain the configured DTIM period
from the AP rather than always hardcoding it to '1', this seems to cause
problems under the following scenarios:
* Preventing association with broken AP's
* Adds latency in roaming
So its better to always use the safe value of '1' for dtim period

With the current save power save implementation we assume a dtim period
of 1.This value is assigned based on a sanity check in the driver
eventhough we had not parsed it from mac80211.This patch obtains the actual
DTIM period from AP by parsing it from mac80211.Yet for handling
multicast traffic we may still have it as fixed rather than parsing it
from mac80211 .This does not breaks power save or anything as the sleep
duration is currently fixed in the driver.This patch may serve to improve
power save in the future by using dtim period for sleep duration and using
correct dtim period adhoc mode.
