tg3: Only allow phy ioctls while netif_running
When tg3 was new, phy accesses through ioctl were allowable at any time.
Then, the driver started shutting down the phy when the device was
closed. Phy accesses would be allowed when the driver first attached to
the device, but then would be forbidden after the device had been up'd
and down'd. After that, management firmware made it illegal to access
the phy unless the driver "owned" the device. Now that most firmware
is being moved over to the APE, it is less clear when phy accesses are
safe.
While it is possible to attempt to identify these conditions and code
the driver to navigate through the pitfalls, it could be perplexing to
the admin why phy accesses work in some cases and not others. This
patch brings some uniformity to the problem by only allowing phy
accesses while the driver has control of the device.

This is caused, because the flushing of the queues takes

We can apply this maximum by passing the drop status to the

After these changes, association times fall within the

rt2x00: Split rt2x00dev->flags
The number of flags defined for the rt2x00dev->flags field,
has been growing over the years. Currently we are approaching
the maximum number of bits which are available in the field.
A secondary problem, is that one part of the field are initialized only
during boot, because the driver requirements are initialized or device
requirements are loaded from the EEPROM. In both cases, the flags are
fixed and will not change during device operation. The other flags are
the device state, and will change frequently. So far this resulted in the fact
that for some flags, the atomic bit accessors are used, while for the others
the non-atomic variants are used.
By splitting the flags up into a "flags" and "cap_flags" we can put all flags
which are fixed inside "cap_flags". This field can then be read non-atomically.
In the "flags" field we keep the device state, which is going to be read atomically.
This adds more room for more flags in the future, and sanitizes the field access methods.

ath9k: fix powersave frame filtering/buffering in AP mode
This patch fixes a long standing issue of pending packets in the queue being
sent (and retransmitted many times) to sleeping stations.
This was made worse by aggregation through driver-internal retransmitting
of A-MDPU subframes.
Previously the hardware tx filter was cleared unconditionally for every
single packet - with this patch it uses the IEEE80211_TX_CTL_CLEAR_PS_FILT
for unaggregated frames.
A sta_notify driver op is added to stop aggregation for stations when they
enter powersave mode. Subframes stay buffered inside the driver, to ensure
that the BlockAck window keeps a sane state.
Since the driver uses software aggregation, the clearing of the tx filter
needs to be handled by the driver instead of mac80211 for aggregated frames.

ath9k: Fix beacon generation on foreign channel
While leaving the oper channel, beacon generation is stopped
by mac80211 and beacon slots are marked as inactive.
During the scan, ath9k configures beacon timers
based on IEEE80211_CONF_OFFCHANNEL which inturn generates
beacon alert even though bslot is inactive.
ath9k fails to disable beacon alert while moving to offchannel
if none of the beacon slot is active. This is causing beacon
transmission on foreign channel. This patch enables swba
based on active bslots.
This issue was reported with two vifs (AP+STA) and triggered
scan in STA vif in unassociated state.

mac80211: add a function for setting the TIM bit for a specific station
This allows a driver to buffer frames for a PS station and tell mac80211
to wake it up even though mac80211 does not have any buffered frames for
it.
This is necessary for properly handling aggregation related buffering,
in ath9k, because the driver needs to keep its frames in order to keep
track of the Block-ACK window.

ath: fix 0x6C for beaconing/passive scan flags based on country IE
The 0x6C regulatory domain is just like the 0x6A regulatory
domain but differs in that 0x6C will allow adhoc and active
scan on its channels only if we are associated to an AP
with a country IE that allows those channels. The
ath_reg_apply_beaconing_flags() does just this -- we respect
the manufacturer's intent on only enabling beaconing modes
of operation if and only if blessed by the country IE.
