54428c57b6 mwifiex: parse WMM IEs from hostapd for mwifiex AP
This patch adds support for parsing WMM IEs from hostapd
and setting them to FW via sys configure command.

Patch also sets wiphy flag to advertise AP uAPSD support.

683b6d3b31 cfg80211: pass a channel definition struct
Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.

Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

42d97a599e cfg80211: remove remain-on-channel channel type
As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.

Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.

47411a06c0 mwifiex: add multi-queue support
This patch adds support for multiple TX queues inside mwifiex
driver. Four different queues according to WMM access categories
are defined for each virtual interface. When a packet is
received from netdev for transmission, tx pending count for
particular queue is incremented and if tx pending count has
reached upper water-mark, this queue is stopped instead of
stopping all queues. Similarly when a packet is successfully
transmitted from device, tx pending count is decremented per
queue and if pending count falls below lower water-mark, queue
operations are again resumed. This ensures that not all
tranmission is blocked if traffic with particular TOS value
suddenly increases.

Also wake all queues after association/IBSS_join/uAP_BSS_start
to enable traffic on all queues.

c8442118ad cfg80211: allow per interface TX power setting
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.

22db24976f Revert "mwifiex: retrieve correct max_power information in reg_notifier handler"
This reverts commit 34202e28fe

We made "34202ee.." because we didn't support custom regulatory rules
at that time. But now we use our own custom regulatory rules, so it
needs to be changed back.

Also, chan->max_power calculations in cfg80211 were broken. Hence we
started using chan->max_reg_power. Now it has got fixed in
following commit.

b0e70c2fb6 mwifiex: minor cleanup and a fix in scan semaphore usage
mwifiex_request_scan() takes care of synchronous internal scan
performed by driver during association.
Currently the semaphore acquired for the scan is unnecessarily
released at the end of different paths. Also, failure paths
returning error code other than "-1" are not considered.

We will release it at the end of routine to fix above issues.

b292219fa5 wireless: use OR operation to set wiphy features
The next patch will introduce a flag that is set
by default in cfg80211 so drivers and mac80211
need to use |= to set features they have so that
they don't clear the already-set feature.

We could set the flag in wiphy_register() instead
of wiphy_new() to avoid this patch, but then the
drivers couldn't *unset* flags they don't want to
use even though the implementation is generic.

1f45b39ece mwifiex: remove redundant code in set channel path
1) Recently we removed set_channel cfg80211 handler. Also, cfg80211
blocks ibss connection requests if ibss network is already started
/joined. Hence the code to restart ibss network in new channel
(mwifiex_drv_change_adhoc_chan() function) becomes redundant.

2) mwifiex_bss_set_channel() function is redundant. It does some
error checking and calculate adhoc start band and adhoc channel.
Cfg80211 already takes care of error checking and provides correct
channel information to the driver. Adhoc start band is already
calculated in mwifiex_set_rf_channel() function.

Other associated code is also removed in this patch.
