The calculated values for the ACK timeout and ACK
consume time are different then the values as
used by the Legacy drivers.

After testing from James Ledwith it appeared that
the calculated values caused a high amount of TX
failures, and the values from the Legacy drivers
were the most optimal to prevent TX failure due to
excessive retries.

The symptoms of this problem:
 - Rate control module always falls back to 1Mbs
 - Low throughput when bitrate was fixed

Possible side-effects (not confirmed but highly likely)
 - Problems with DHCP
 - Broken connections due to lack of probe response

This should fix at least:
Kernel bugzilla reports: [13362], [13009], [9273]
Fedora bugzilla reports: [443203]
but possible some additional bugs as well.

The bss_info_changed() callback function no longer needs
to be atomic. Remove the scheduled work structure and
call into the driver directly.

Additionaly this makes the DRIVER_REQUIRE_SCHEDULED
flag redundant so it can be removed.

In the TX descriptor the Packet ID must not be 0,
so add 1 to the ID. The wireless CLI ID is not allowed
to be 0 either, but also must be initialized with the
wcid value rather then keyid.

When beacon is being updated to refresh TIM (AP mode), beacon frames are
de-synchronizing (i.e. two neighbor beacon frames - before and after
update - are being transmitted with a wrong time interval).
That is because xxx_write_beacon should disable beacon generation only
while beacon data are being uploaded to the device, but it should not
disable the beacon clock.

Implement set_tim callback for all rt2x00 drivers, this makes the
device wake up powersaving stations properly while in AP mode.

The only way to update the beacon is by simply calling mac80211 and
requesting the new beacon. This means the set_tim() event is mostly the
same as a beacon_done() event which was already defined in rt2x00lib.

Remove the input_polldev from rt2x00 and replace it with
the rfkill interface offered by the wiphy structure. This
simplifies the entire rfkill handling in rt2x00 and allows
us to remove the CONFIG_RT2X00_LIB_RFKILL option and always
enables rfkill capabilities.
