The channel_type really doesn't need to be the only member in
a new structure, so remove the struct. Additionally, remove
the _CONF_CHANGE_HT flag and use _CONF_CHANGE_CHANNEL when the
channel type changes, since that's enough of a change to require
reprogramming the hardware anyway.

Not all drivers are capable of passing properly aligned frames,
in particular with mesh networking no hardware will support
completely aligning it correctly.

This patch adds code to align the data payload to a 4-byte

* Sync qcu.c with legacy-hal
* Add some more comments
* Set QCU mask to save power (QCU mask controls which QCUs are attached
  to each DCU, we do a 1:1 mapping)

TODO: Use max QCU from EEPROM, further sync with legacy-hal and sam's

Okay, here is the first of the five patches. After applying all
of them you should be able to build/join huge city mesh networks
(e.g. with the OLSR protocol) with the most of the mac80211 wireless
drivers by setting a fixed BSSID in the ad hoc mode. (If you found no
other bug/problem.) This was not specified in the original standard,
but is a widely used de facto standard.

The first patch now completely disallow to set multicast MAC addresses
as BSSID. The behavior before was really strange.

for that reason RFKILL support should be entirely removed.

first time, the tx power limit is taken from min(chan->max_power,
local->hw.conf.power_level) which is not what we want. This patch

When we try to change the channel in ath9k its because
either the configuration indicates we *have* changed
channels or HT configuration has changed. In both cases
we want to do a reset. Either way mac80211 will inform us
when we want to actually change the channel so trust those
calls.

Although in the patch it may seem as I am doing more code

The only left users are for timing for ACK timeout, slotime and

these values per mode and since as only will use A and G
we can depend on the band to get the appropriate values.

We note that we should be using a different clock rate value
for CCK, we can do this in separate patch, currently this is
being disregarded and should only affect when we want to
change the default ACK/CTS timeout or slot time and stuck

The NOISE_FLOOR array we have is mode specific, and the only
possible indexed values are A, B and G. The mode routine only
can return G or A, so this is band specific. Then since the
values for A and G (5ghz or 2ghz) are the same (-96) we simply
remove the array and use a static value.

If we later determine we want to use special values for
HT configurations we can use the new mac80211 conf_is_ht*()
