Some of the newer Broadcom chipsets have longe names like BCM43224,
BCM43225, etc. However Broadcom decided to keep using u16 for storing
them. Use %X or %d depending on chip_id value to avoid BCMA8D8, etc.

Some P2P scans are not allowed to advertise
11b rates, but that is a rather special case
so instead of having that, allow userspace
to request the rate sets (per band) that are
advertised in scan probe request frames.
Since it's needed in two places now, factor
out some common code parsing a rate array.

Harshal Chhaya discovered during network tests, that
several of his clients dropped-off the network. The
captured packets shows that the beacons sent by the
AP are at a much lower power than the other data
packets.
The reason for this mishap: The driver never updated
the beacon phy register, so all beacons were always
sent at the lowest power.

Add tx_conf array to save the current tx queues
configuration, and reconfig it on resume (ieee80211_reconfig).
On resume, the driver is being reconfigured. Without
reconfiguring the tx queues as well, the driver might

instead of uapsd).

The upper layer receives a pointer to an iwl_rx_mem_buffer. I would prefer the
upper layer to receive a pointer to an iwl_rx_packet, but this is impossible
since the Rx path needs to add the address of the page to the skb.
I may find a solution later.
All the pre_rx_handler and notification code has been moved to the upper layer.

When suspending with all netdevs down, the device
is stopped but we still call a number of driver
callbacks that the driver might not expect. The
same happens during resume, we might call a few
callbacks without starting the driver. Fix this
by checking open_count around more things and
exiting quickly if it is 0.
Also, while at this I noticed that the coverage
class isn't reprogrammed after resume, so add
that.
