Add a flag to struct txdata_entry_desc that specifies whether an ack for the
frame is to be expected. Use this flag to set the ACK bit in the tx descriptor.
Previously, the ACK bit could be set incorrectly on CTS-to-self frames, so they
caused retries and were reported to be failed in the txdone handlers.

There is a buffer, csr_cache which is used to hold copies of data being passed
to the USB stack which can get corrupted if multiple threads attempt to access
CSR registers simultaneously. There is also the possibility if multiple
threads try to access BBP or RF registers for the multiple USB operations
needed to get interleaved leading to incorrect results. This patch introduces
a mutex to prevent such simultaneous access. The interleaved access problem
may also affect the PCI devices but if so that will be handled in a follow-up
patch.

Based on investigation of the legacy drivers, I have made the
following assumptions of the antenna setup:
- R77 is the TX antenna configuration
- RF2529 fetches default antenna selection from NIC eeprom word
With these assumptions we can change the antenna configuration
to correctly read both antenna setup values and correctly
configure the antenna. And we can now also configure the antenna
for RF2529 without a double antenna.

mac80211 has 3 values for the antenna setup:
0 - default
1 - use antenna 1
2 - use antenna 2
This means that rt2x00 should store the default value
from the EEPROM somwhere and use that when mac80211 indicates
that the antenna setup is 0.
This also implies that rt2x00 should no longer write the
hw->config.antenna_sel_* values based on the EEPROM input.
This also adds the basis in rt2x00lib for correct software

Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above.

Some versions of gcc replace strstr() calls with a single-character `needle'

| drivers/built-in.o: In function `libertas_parse_chan':
| linux/drivers/net/wireless/libertas/debugfs.c:209: undefined reference to `strchr'
| drivers/built-in.o: In function `libertas_parse_ssid':
| linux/drivers/net/wireless/libertas/debugfs.c:260: undefined reference to `strchr'

As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.
Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.
To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

Also make sure that when the packet filter is scheduled, the

will update the packet filter instead of failing at the check:

ipw2200 makes extensive use of background scanning when unassociated or
down. Unfortunately, the firmware sends scan completed events many
times per second, which the driver pushes directly up to userspace.
This needlessly wakes up processes listening for wireless events many
times per second. Batch together scan completed events for
non-user-requested scans and send them up to userspace every 4 seconds.
Scan completed events resulting from an SIOCSIWSCAN call are pushed up
without delay.

As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses
udev by presenting 2 interfaces with the same MAC address. Also, at the time
of detection, the 'type' attribute is 1, identical to other hostap interfaces.
The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is
not set until after registration.
Setting it before register_netdev() is called allows us to avoid this
confusion. We can do this by propogating the HOSTAP_INTERFACE type through
to hostap_setup_dev().

This patch removes redundant memset in rate scale. In rs_alloc_sta,
kzalloc is used so the memset can be avoided. In rs_rate_init, it is
a bug fix since it overrides everything set in other handlers namely

As pointed out by Modestas Vainius the link tuner
could continue working while the radio is already
down. This because at the start of disable_radio
the ENABLED_RADIO flag is cleared and causes the
toggle_rx to skip the stop_link_tuner() call.
This will add a check to the start of the link tuner
which will automatically stop the link tuner when the
radio is disabled.

Drivers are currently supposed to keep track of monitor
interfaces if they allow so-called "hard" monitor, and
they are also supposed to keep track of multicast etc.
This patch changes that, replaces the set_multicast_list()
callback with a new configure_filter() callback that takes
filter flags (FIF_*) instead of interface flags (IFF_*).
For a driver, this means it should open the filter as much
as necessary to get all frames requested by the filter flags.
Accordingly, the filter flags are named "positively", e.g.
FIF_ALLMULTI.
Multicast filtering is a bit special in that drivers that
have no multicast address filters need to allow multicast
frames through when either the FIF_ALLMULTI flag is set or
when the mc_count value is positive.
At the same time, drivers are no longer notified about
monitor interfaces at all, this means they now need to
implement the start() and stop() callbacks and the new
change_filter_flags() callback. Also, the start()/stop()
ordering changed, start() is now called *before* any
add_interface() as it really should be, and stop() after
any remove_interface().
The patch also changes the behaviour of setting the bssid
to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING
is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed
and the filter flag FIF_BCN_PRBRESP_PROMISC introduced.
This is a lot more efficient for hardware like b43 that
supports it and other hardware can still set the BSSID
to all-ones.

This change cleans up the radio-related messages in several ways.
(1) The state of the rfkill switch is assumed to be on, rather than
tested. Now, any user without such a switch will not see any
messages. For devices with such a switch, a message will be
logged only if the initial state is off, or if the switch is toggled.
(2) The routine for testing the switch state is no longer inline.
(3) The LED handling routine is simplified.
(4) The "Radio turned off" message that has confused some users has been
changed to "Radio initialized".
This patch is patterned after a similar change to b43 by Michael Buesch.
