The patch "mac80211: fix PS-poll response race" somehow broke
broadcast buffering in a funny way.
During normal operation - stations are awake - the firmware refused
to transmit broadcast frames and reported P54_TX_PSM_CANCELLED.
But everything worked as soon as one station entered PSM.
The reason:
The stack sets IEEE80211_TX_CTL_SEND_AFTER_DTIM for outgoing
broadcast frames as soon as a station is marked as sleeping.
This flag triggers a path which will reroute these frames
into p54's "content after beacon" queue, which is designed
to cope with the demands for psm.
This patch restores the old behavior.
IEEE80211_TX_CTL_CLEAR_PS_FILT will once again be used to signalize
the firmware to ignore the ps canceling for certain frames.

Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.
A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

The mac80211 workqueue exists to enable mac80211 and drivers
to queue their own work on a single threaded workqueue. mac80211
takes care to flush the workqueue during suspend but we never
really had requirements on drivers for how they should use
the workqueue in consideration for suspend.
We extend mac80211 to document how the mac80211 workqueue should
be used, how it should not be used and finally move raw access to
the workqueue to mac80211 only. Drivers and mac80211 use helpers
to queue work onto the mac80211 workqueue:
* ieee80211_queue_work()
* ieee80211_queue_delayed_work()
These helpers will now warn if mac80211 already completed its
suspend cycle and someone is trying to queue work. mac80211
flushes the mac80211 workqueue prior to suspend a few times,
but we haven't taken the care to ensure drivers won't add more
work after suspend. To help with this we add a warning when
someone tries to add work and mac80211 already completed the
suspend cycle.
Drivers should ensure they cancel any work or delayed work
in the mac80211 stop() callback.

When a station queries us for a PS-poll response, we wrongly
queue the frame on the virtual interface's queue rather than
the pending queue.
Additionally, fix a race condition where we could potentially
send multiple frames to the sleeping station due to using a
station flag rather than a packet flag. When converting to a
packet flag, we can also convert p54 and remove the filter
clearing we added for it.

Disabling the receiver logic with P54_FILTER_TYPE_RX_DISABLED is not
supported by all firmwares. However we have an alternative: hibernation.
And the only side effect - so far - is a bit less power consumption. WIN!

The patch fixes a problem when the (Soft)LED stayed on after the module was unloaded.
It turned out that the USB core disables all endpoints before calling the disconnect method.
So it was impossible to switch off the radio & LEDs.

Since the standards only define 12 legacy rates, 32 is certainly
a sane upper limit and we don't need to use u64 everywhere. Add
sanity checking that no more than 32 rates are registered and
change the variables to u32 throughout.

This is the same patch for p54spi.
It removes all N800/N810 specific code from p54spi, so the driver can be used on
other architectures, or configurations as well.

A recent change in the usb core "USB: change interface to usb_lock_device_for_reset()"
conflicts with "p54usb: utilize usb_reset_device for 3887".
Sadly, we have to call usb_reset_device before we can upload the firmware on 3887.
Unless someone figures out how to reliably stop the 3887 so the hardware is still usable
next time we want to start it.

Usually every prism54 design hardware has a tiny eeprom chip in which all
device specific data for calibration and link-tuning is stored.
The stlc45xx chips are the only exception.

mac80211 reserves 24 bytes in skb->cb for the driver.
So far, we only used them to keep track of used and free device memory.

Old firmwares had no problems processing frames which filled eighth of the memory window.
However we have to be a bit more careful with fat frames when we talk to new firmwares.
Apart from that, I confess the old logic was a bit weird and not very sophisticated.
