Implement triggers inside rt2x00 itself based
on input from mac80211. This replaces the method
of using the mac80211 trigger events which do
not work for USB drivers due to the scheduling
requirement.
After this patch RT2500USB_LEDS and RT73USB_LEDS
no longer need to be tagged as broken since they
now support LED handling again without having to
check for in_atomic().

The TO_DS filter does not only depend on the FIF_PROMISC_IN_BSS flag
provided by mac80211, but also on the intf_ap_count count.
This makes sense, since when Master mode is active, we should all frames
that are send to the active AP (the device itself).
This means that when an interface is added we should force the
packet filter to be updated during the next mac80211 call of
configure_filter() to make sure the intf_ap_count field is checked.

Confirm sleep event: they come very regularly, eventually several times per
second. Therefore we want to send the config command as fast as possible.
The old code pre-set the command in priv->lbs_ps_confirm_sleep. However, the
byte sequence to be sent to the hardware is the same for all interfaces. So
this patch make this an extern structure, initialized at module load time.
Config wake event: normal conversion to a direct command. However, I don't know
how to trigger a "HOST AWAKE" event from the firmware, so this part is
untested.

This patch add LEDS support to 3965 and 4965 drivers. It is based on
led trigger and class. For our drivers we needed to avoid two things.
1- We receive led trigger on/off on each Rx\Tx frame. In our driver
we can not call led command like that. In this driver once driver
receive a start of traffic it call the led command to start blinking
then we count all bytes of Tx and Rx frame, after two second we count the
blink rate of last two second then id blink rate changed we call the led
commands
2- Since we can call led command very often, we make sure we call the
led command after we receive the statistics notification so
we don't need to wake up the ucode id it is in sleep state.
This patch was tested with 4965 and 3945.

Some hardware never seem to accept the "goto sleep" command, since the legacy
drivers don't have suspend and resume handlers the entire code for it was
basically a educated guess (based on the "enable radio" code).
This patch will only print a warning when the "goto sleep" command fails, and
just continues as usual. Perhaps that means the device will not reach a sleep
state and consumes more power then it should, but it is equally possible it
simply needs some seconds longer to sleep. Anyway, by making the command
non-fatal it will not block the rest of the suspend procedure.

rt73usb and rt2500usb used in_atomic to determine
if a configuration step should be rescheduled or not.
Since in_atomic() is not a valid method to determine
if sleeping is allowed we should fix the way this is handled
by adding a new flag to rt2x00.
In addition mark LED class support for the drivers broken
since that also uses the broken in_atomic() method but
so far no solution exists to have LED triggers work only
in scheduled context.

It has been observed on rt2500pci hardware that some
frames received with signal 0x0C do not have the OFDM
flag set.
Signals can have 2 meanings:
1) The PLCP value
2) The bitrate * 10
For rt2500pci (1) is for frames received with a OFDM rate,
and (2) is for frames received with a CCK rate.
But 0x0C is a invalid bitrate value but is a valid PLCP
value for 54Mbs (obvious OFDM rate).
This means that it is possible that the hardware does not
set the OFDM bit correctly under all circumstances.
This results in rt2x00 failing to detect the rate and
mac80211 triggering a WARN_ON() and dropping the frame.
To bypass this, print a warning when such a frame is received,
and reset the rate to the lowest supported rate for the current band.
