Cooked monitor interfaces cannot currently receive Probe Request
frames when the interface is in station mode. However, we do not
process Probe Request frames internally in the station MLME, so there
is no point in queueing the frame here. Remove Probe Request frames
from the queued frame list to allow cooked monitor interfaces to
receive these frames.

As a holdover from earlier code when we used to set
the power limit to '0' after a reset to configure the
default transmit power, ath5k interprets txpower=0 as
12.5 dBm. Fix that by just passing 0 through.

Please be gentle, I'm a fs developer and this is my first foray into drivers, as
I'm tired of building ralinks driver everytime I update my kernel. Whenever I
load the rt2800pci driver my box bogs down, and a few printk's later I
discovered its because I was getting 10's of thousands of TBTT interrupts a
second. I discovered this was because we were setting the beacon timer to 0,
which is apparently what TBTT keys off of. It seems to me that we should only
be enabling TBTT when we are in a beacon transmitting mode, which from what I
can tell is in AD-HOC and other such modes where the mac80211 layer would have
given us a proper beacon_int to set the beacon timer to instead of 0. So this
is my fix, only enable TBTT if our sync mode is for beacon. This makes it so my
box doesn't die everytime I load the rt2800pci driver. Let me know if this is
acceptable, I just learned all these terms about 15 minutes ago via wikipedia,
so I really am not familiar with how this stuff is supposed to work. Thanks,

Current tree hits a BUG_ON in rt2x00_regbusy_read, because the eFuse EEPROM
reading code of rt2800lib uses the function without the csr_mutex locked.
Fix this by locking the csr_mutex for the of the EEPROM reading cycly and
using the _lock variants of the register reading and writing functions.
This also introcudes the register_read_lock function pointer in the
rt2800_ops structure.

This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
ops that a driver can implement. The goal of this command is to allow a
drivers to report channel survey data (e.g. channel noise, channel
occupation).
For now, only the mechanism to report back channel noise has been
implemented.
In future, there will either be a survey-trigger command --- or the existing
scan-trigger command will be enhanced. This will allow user-space to
request survey for arbitrary channels.
Note: any driver that cannot report channel noise should not report
any value at all, e.g. made-up -92 dBm.

Jumbograms are frames put together linked together through
more than one descriptor. For example ath9k_htc will use this
to send from the target a large frame split up into 2 or more
segments. The driver then would be in charge of putting the
frame back together.
When jumbograms are constructed the rx_stats->rs_more will
bet set and rx_stats->rs_status will not have any valid content
as the actual status will only be avialable at the end of
the chained descriptors.

ath9k and ath9k_htc share a lot of common hardware characteristics.
They only differ in that ath9k_htc works with a target CPU and ath9k
works directly with the hardware. ath9k_htc will do *some* things in
the firmware, but a lot of others on the host.
The common 802.11n hardware code is already shared through the ath9k_hw
module. Common helpers amongst all Atheros drivers can use the ath module,
this includes ath5k and ar9170 as users. But there is some common driver
specific helpers which are not exactly hardware code which ath9k and
ath9k_htc can share. We'll be using ath9k_common for this to avoid
bloating the ath module and the common 802.11n hardware module ath9k_hw.
We start by sharing skb pre and post processing in preparation for a hand
off to mac80211.
