When modifying a MAC, we update its beacon system time which
is taken as a base to calculate TBTT. The firmware doesn't use
the new timestamp because the time is never used after the MAC
and broadcast station were added, but it is safer to not rely
on this and avoids the overhead of reading the register every
time the MAC is updated.

1. For P2P Device filter in only probe requests.
2. For station mode filter in all group cast frames,
   and in addition beacons as long as we are not associated.
3. For AP/GO filter in all group cast and in addition probe
   requests.

The current fw doesn't currently support cts to self. There
is a bug in the fw that prevents us from using cts to self.
Use full protection (including RTS) for now.

For the firmware to know when DTIM beacons arrive
we have to program the DTIM time in TSF and system
time in the MAC context. Since mac80211 now tracks
the different times (on demand), this becomes easy.

If we haven't heard a beacon before we associate we can
still start the association process and set the MAC in
the firmware to associated only after having received a
beacon with DTIM period by reacting to the new change
flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.

This reduces the association time in these cases.

Newer firmware revisions have a completely new
firmware API. This is the new driver for this
new API.

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
