Only WoW filters for the first vif were being set, causing failures to
wake up on any concurrent connected vifs. Handle all per-vif suspend
and resume tasks.
Since cfg80211 issues user wow filters on a per-wiphy basis, set any
custom filters on all connected vifs.
Starting WoW in firmware and setting host sleep mode is still handled on
a global per-phy level. The first vif is always used for bookkeeping
regardless of whether it is connected or not.
WoW is cancelled if no connected vifs are found.
No firmware capability bits or API bump is needed for this patch, as
setting filters for vifs with index > 0 will simply overwrite the index
0 filters in the current implementation. While not correct, this is
identical to the existing behavior.

ath6kl was incorrectly assuming that IEEE80211_NUM_BANDS will always be 2
and used that also in the firmware WMI interface definitions. But after
the support for 60 GHz was added to cfg80211 IEEE80211_NUM_BANDS changed to 3
and this can cause all sort of problems, possibly even memory corruption.
I only found this during code review and didn't notice any bugs, but I'm
sure there are a few lurking somewhere.
To fix this rename unused A_NUM_BANDS to ATH6KL_NUM_BANDS, which is
always defined to be 2, and use that in WMI.

When a firmware error occurs, don't just abort synchronous
commands but also return an error (-EIO) and block any new
commands as well. Currently, an error is only returned if
WANT_SKB was set which is confusing and can lead to issues.
Blocking is done until a new firmware image is loaded.

No HCMD can be sent while RFKILL is asserted. If a SYNC
command is running while RFKILL is asserted the fw will
silently discard it. This means that the driver needs to
wake the process that sleeps on the CMD_SYNC.
Since the RFKILL interrupt is handled in the transport layer
and the code that sleeps in CMD_SYNC is also in the transport
layer, all this logic can be handled there.
This simplifies the work of the op_mode.
So the transport layer will now return -ERFKILL when a CMD
is sent and RFKILL is asserted. This will be the case even
when the CMD is SYNC. The transport layer will return
-ERFKILL straight away.

During hardware restart, all interfaces are iterated even
though they haven't been re-added to the driver, document
this behaviour. The same also happens during resume, which
is even more confusing since all of the interfaces were
previously removed from the driver. Make this optional so
drivers relying on the current behaviour can still use it,
but to let drivers that don't want this behaviour disable
it.
Also convert all API users, keeping the old semantics
except in hwsim, where the new normal ones are desired.

The TX power setting is currently per wiphy (hardware
device) but with multi-channel capabilities that doesn't
make much sense any more.
Allow drivers (and mac80211) to advertise support for
per-interface TX power configuration. When the TX power
is configured for the wiphy, the wdev will be NULL and
the driver can still handle that, but when a wdev is
given the TX power can be set only for that wdev now.

To use mac80211_hwsim for testing channel contexts it
has to support them, and for that it has to support
hw scan and hw-remain-on-channel.
Since it's pure software, the off-channel activities
are really not off-channel but listening and sending
on a second channel. Also, the multi-channel isn't
really doing TDM, it's just on both channels at the
same time.
For testing purposes, you can specify the number of
concurrent channels with a module parameter, it is
set to one by default. When set to two or more, the
userspace API for wmediumd is disabled as it has no
provisions for multi-channel yet.

Set tx packet timestamp to 0 in following scenarios:-
- All packets in STA mode
- Mgmt packets in AP mode
- Eapol packets in AP mode
In STA mode, this field is unused in the firmware. In AP
mode, we should not be expiring mgmt and eapol frames.
Setting timestamp to 0 will ensure that.

ksdioirqd has higher priority than kworker. Process RX packets
in SDIO IRQ thread (ksdioirqd/mmcX) directly instead of deferring
the work to kworker to avoid the extra latency.
This improves TCP throughput 15~20% on an ARM platform with SDIO
2.0 controller.

Firmware events are passed to wl_cfg80211 module associated with
the primary net device. With virtual interface support events can
be received for different interfaces, ie. struct brcmf_if instances.
Pass it in the event to determine appropriate net device associated
with the event.
