4fa0043731 mac80211: Fix HT rate control configuration
Handling HT configuration changes involved setting the channel
with the new HT parameters and then issuing a rate_update()
notification to the driver.

This behavior changed after the off-channel changes. Now, the channel
is not updated with the new HT params in enable_ht() - instead, it
is now done when the scan work terminates. This results in the driver
depending on stale information, defaulting to non-HT mode always.

Fix this by passing the new channel type to the driver.

b08dfd0435 iwlwifi: load firmware asynchronously before mac80211 registration
At the wireless summit in Portland we discussed a way of
loading firmware asynchronously from ->probe() before
registration to mac80211, in order to register with the
wireless subsystems with complete information in cases
where firmware is required to know parameters.

This is not yet the case in iwlwifi, but for some new
features we're working on it will be the case since
those will only be supported by new firmware images.

Hence, to start with, convert iwlwifi to load firmware
asynchronously from probe, unbinding the device when
firmware loading fails, and only registering with the
wireless subsystems after firmware has been loaded
successfully.

Future patches will hook into this to register the
new firmware capabilities, depending on the firmware
API version.

9e3bd91908 b43: fall back gracefully to PIO mode after fatal DMA errors
This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.

The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

7bfbae10dc ath9k: disable RIFS search for AR91xx based chips
While ath9k does not support RIFS yet, the ability to receive RIFS
frames is currently enabled for most chipsets in the initvals.
This is causing baseband related issues on AR9160 and AR9130 based
chipsets, which can lock up under certain conditions.

This patch fixes these issues by overriding the initvals, effectively
disabling RIFS for all affected chipsets.

ab9bdc34d6 Revert "iwlwifi: Monitor and recover the aggregation TX flow failure"
This reverts commit 1db5950f1d.

The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure"
is to first detect when data transmission stalls and then to recover from
this situation with a reset of the radio or the firmware, depending on how
bad the transmission failures are.

Unfortunately we have found that this change causes excessive resets with
its current detection algorithm. It also performs its recovery action when
none is really needed, like when we are not associated.

Revert this change until the issues have been addressed.

Check the frame control for ieee80211_is_data_qos() is true before
counting the number of tfds can be free, the tfds_in_queue only
increment when ieee80211_is_data_qos() is true before transmit; so it
should only decrement if the type match.

Remove ieee80211_is_data_qos check for frame_ctrl in tx_resp to avoid
invalid information pass from uCode.

d8728ee919 ath9k: fix beacon timer restart after a card reset
In AP mode, ath_beacon_config_ap only restarts the timer if a TSF
restart is requested. Apparently this was added, because this function
unconditionally sets the flag for TSF reset.

The problem with this is, that ath9k_hw_reset() clobbers the timer
registers (specified in the initvals), thus effectively disabling the
SWBA interrupt whenever a card reset without TSF reset is issued
(happens in a few places in the code).

This patch fixes ath_beacon_config_ap to only issue the TSF reset flag
when necessary, but reinitialize the timer unconditionally. Tests show,
that this is enough to keep the SWBA interrupt going after a call to
ath_reset()

5c0ba62fd4 ath9k: fix rate control fallback rate selection
When selecting the tx fallback rate, rc.c used a separate variable
'nrix' for storing the next rate index, however it did not use that as
reference for further rate index lowering. Because of that, it ended up
reusing the same rate for multiple multi-rate retry stages, thus
decreasing delivery probability under changing link conditions.

This patch removes the separate (unnecessary) variable and fixes
fallback the way it was intended to work.
This should result in increased throughput and better link stability.

orinoco_cs and hostap_cs.

5e2f75b899 iwlwifi: set HT flags after channel in rxon
The HT extension channel settings require priv->staging_rxon.channel to be
accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel
and thus HT40 could be broken unless another call to iwl_mac_config came in.

This problem was recently introduced by "iwlwifi: Fix to set correct ht
configuration"

The particular setting in which I noticed this was monitor mode:

	iwconfig wlan0 mode monitor
	ifconfig wlan0 up
	./iw wlan0 set channel 64 HT40-
	#./iw wlan0 set channel 64 HT40-
	tcpdump -i wlan0 -y IEEE802_11_RADIO

would only catch HT40 packets if I issued the IW command twice.

From visual inspection, iwl_set_rxon_channel does not depend on
iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

ID's for these devices. However, to allow for testing it is good to still
have them available, although disabled by default.
Make support for these device configuration options that default to off.

For rt2800usb a 3rd class of devices is added, which are the unknown
devices. For these devices it is known that they are either based on
rt28xx, rt30xx or rt35xx, but it is not known on what chipset exactly.
These devices are disabled by default as well, until it can be established
on what chipset exactly they are based.

49e721ec6c rt2x00: rework RT chipset and revision determination for PCI an SOC devices.
The recent rt2800 devices are no longer really identified by their PCI
ID's, but rather by the contents of their CSR0 register. Also for the
other chipsets is the contents of this CSR0 register important.
Change the chipset determination logic to be more aligned with the rt2800
model.
Preparation for the support of rt3070 / rt3090 based devices.

fafaf31bf9 iwlwifi: fix AMSDU Rx after paged Rx patch
Previous patch "use paged Rx" broke AMSDU Rx functionality. If an AP
sends out A-MSDU packets the station will crash.  Fix it by linearizing
skbuff for AMSDU packet before handing it to mac80211 since mac80211
doesn't support paged skbuff.

This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2155

42c4568a4a ath9k: add a workaround for ack timeout issues
Adding support for setting the coverage class in some cases broke
association and data transfer, as it overwrote the initial ACK timeout
value from the initvals with a smaller value.
I don't know why the new value works in 5 GHz (matches the initval
there), but not in 2.4 GHz (initvals use 64us here), so until the
problem is fully understood, the value should be increased again.

1db5950f1d iwlwifi: Monitor and recover the aggregation TX flow failure
This change monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the expected_
ack_count also drops.  At the same time, the aggregated ba_timeout (the number
of ba timeout retries) also rises.  If the actual_ack_count/expected_ack_count
ratio is 0 and the number of ba timeout retries rises to 16, no tx packets
(tcp, udp, or ping - icmp) can be delivered.  The driver recovers from this
situation by reseting the uCode firmware.  If the actual_ack_count/expected_
ack_count ratio drops below 50% (but not 0) and the aggregated ba_timeout
retries just exceed 5 (but not 16), then the driver can reset the radio to
bring the throughput up.

4843b5a731 iwlwifi: reset card during probe
To ensure that card is in a sane state during probe we add a reset call.
This change was prompted by users of kdump who was not able to bring up the
wireless driver in the kdump kernel. The problem here was that the primary
kernel, which is not running at the time, left the wireless card up and
running. When the kdump kernel starts it is thus possible to immediately
receive interrupts from firmware after registering interrupt, but without
being ready to deal with interrupts from firmware yet.

bbcbb9ef97 iwlwifi: fix scan race
There is a problem if an "internal short scan" is in progress when a
mac80211 requested scan arrives. If this new scan request arrives within
the "next_scan_jiffies" period then driver will immediately return success
and complete the scan. The problem here is that the scan has not been
fully initialized at this time (is_internal_short_scan is still set to true
because of the currently running scan), which results in the scan
completion never to be sent to mac80211. At this time also, evan though the
internal short scan is still running the state (is_internal_short_scan)
will be set to false, so when the internal scan does complete then mac80211
will receive a scan completion.

Fix this by checking right away if a scan is in progress when a scan
request arrives from mac80211.
