This patch removes unnecessary parameter in ieee80211_beacon_add_tim() and
removes unneeded definition and assignment for bdev (instance of net_device) in
ieee80211_beacon_get() and in ieee80211_get_buffered_bc()
(all in tx.c).

This patch is necessary in order to provide a proper Access point support for p54.
Unfortunately for us, there is no documented way to disable the interfering
power save buffering mechanism in firmware completely.
Therefore we give in and notify the driver through our new sta_notify_ps callback,
so that we can update the filter state.

When a station goes to PS mode to scan, it will then send
probe requests without the PS bit set. mac80211 will take
that as indication that the station woke up, but it didn't.
This patch changes mac80211 to only consider doze->wake
transitions on data frames to to fix that issue.

This patch reorders calls during disassociation in
ieee80211_set_disassoc function.
Since sta_info_unlink calls sta_notify(REMOVE) it will
remove the station representing AP from the driver before
it has disassociated from it using bss_info_changed callback.

It seems like proper etiquette to let other stations know when we are
going down in either STA or IBSS mode. This also notifies userland, so
wpa_supplicant doesn't get confused.

After fixing zd1211rw: use unaligned safe memcmp() in-place of
compare_ether_addr(), I started to see kernel log messages detailing
unaligned access:
Kernel unaligned access at TPC[100f7f44] sta_info_get+0x24/0x68 [mac80211]
As with the aforementioned patch, the unaligned access was eminating
from a compare_ether_addr() call. Concerned that whilst it was safe to
assume that unalignment was the norm for the zd1211rw, and take
preventative measures, it may not be the case or acceptable to use the
easy fix of changing the call to memcmp().
My research however indicated that it was OK to do this, as there are
a few instances where memcmp() is the preferred mechanism for doing
mac address comparisons throughout the module.

When a disassoc packet is received from the AP with a reason code of
'leaving the BSS', mac80211 should go into DISABLED state just as it
would do if the AP suddenly went away for some reason, as that is what
will happen shortly after the AP leaves anyway.

In commit 9ea2c74 named "mac80211/drivers: rewrite the rate control API",
the meaning of status.rates[i].count was changed from number of retries
to total number of tries. As a result, the pid rate-setting algorithm fails
because every packet appears to have needed a retransmit.

mac80211's ieee80211_register_hw() is often called within the
probe path so it cannot assume the device's driver structure
has been attached yet so to create a workqueue instead of
using driver->name use the wiphy's phy%d name. The name doesn't
really matter anyway.
This should fix sporadic oopses found when we race to beat the
driver pointer setting. Not even sure how this was working properly.

This adds country IE parsing to mac80211 and enables its usage
within the new regulatory infrastructure in cfg80211. We parse
the country IEs only on management beacons for the BSSID you are
associated to and disregard the IEs when the country and environment
(indoor, outdoor, any) matches the already processed country IE.
To avoid following misinformed or outdated APs we build and use
a regulatory domain out of the intersection between what the AP
provides us on the country IE and what CRDA is aware is allowed
on the same country.
A secondary device is allowed to follow only the same country IE
as it make no sense for two devices on a system to be in two
different countries.
In the case the AP is using country IEs for an incorrect country
the user may help compliance further by setting the regulatory
domain before or after the IE is parsed and in that case another
intersection will be performed.
CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
present.

Mesh interfaces are currently opened with the FIF_ALLMULTI rx filter flag set,
however there is no BSSID in mesh so BSSID filtering should be disabled by
setting the FIF_OTHER_BSS flag as well. Also explicitly call
ieee80211_configure_filter for mesh.
