b26e395038 rndis_wlan: remove unneeded variables
We never use the "len" variable.

41eedf39df rndis_wlan: integer overflows in rndis_wlan_do_link_up_work()
If "offset" is negative then we can get past this check:
	if (offset > CONTROL_BUFFER_SIZE)
Or if we pick a very high "req_ie_len" then we can get around the check:
	if (offset + req_ie_len > CONTROL_BUFFER_SIZE)

I made "resp_ie_len" and "req_ie_len" unsigned.  I don't know if it was
intentional that they were signed in the original.

5809802180 b43: prevent firmware on bcm5354 from taking over wrong GPIO pins
When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent
firmware >= 478.104 it runs out of memory after a very short time in
OpenWrt after doing an active scan or any thing else where packages are
send. This was cased by a gpio misconfiguration, the firmware triggered
the GPIO pins used for buttons on some devices and that caused an other
driver (OpenWrt diag) listening for these buttons irqs to send many
messages to the user space.
This patch fixes the bug for my devices (Asus WL-520GU) and makes it
work with firmware 666.2. Now the firmware just uses LED GPIO pin
number 1 and not the button pins any more.

This is the GPIO Pin layout used on my device, see [0].
GPIO pin layout:
pin#    name    type
0       power   led
1       wlan    led
2       reset   button
3       ses     buttom

This is the nvram configuration output of "nvram show |grep gpio"

related nvram configuration:
wl0gpio2=11
wl0gpio3=11
wl0gpio0=11
wl0gpio1=0x02
reset_gpio=2

be0b281e8f mwifiex: fix bug in wildcard scan handling
Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.

When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.

Also, use SSID list pointer provided by stack directly, instead
of copying SSID's to local structure.

driver tries to connect using open mode. The association is failed
if AP is configured in shared mode.

This patch adds code to try association using shared mode as well if

Now since we returned exact error code in association response handler
(instead of -1), corresponding changes are done in

TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also

deauth, disassoc and action frames.)

Previously, mac80211 would let the MMPDU through
but not set the flag so drivers supporting some
hardware aids for avoiding the PS races would
then reject the frame.

02f1434d4e zd1211rw: wait between setting hash table and powering radio on
I am running Debian testing kernel 3.1.0-1-amd64, using a 079b:0062 Sagem
XG-76NA 802.11bg stick.

Upon zd1211rw interface
bringup (ifconfig wlan0 up) I get the following timeout:

[  950.330573] zd1211rw 1-3:1.0: phy2
[  955.108510] zd1211rw 1-3:1.0: firmware version 4725
[  955.148532] zd1211rw 1-3:1.0: zd1211b chip 079b:0062 v4810 high 00-19-70
AL2230_RF pa0 g--NS
[snip]
[  955.204072] zd1211rw 1-3:1.0: error ioread32(CR_REG1): -110

A second ifconfig wlan0 up brings the interface up without problems.

After a bit more debugging, the call trace is the following:

[10241.028130] zd1211rw 1-3:1.0: zd_chip_lock_phy_regs: error
ioread32(CR_REG1): -110
[10241.028140] zd1211rw 1-3:1.0: zd_switch_radio_on: failed to lock PHY regs
[10241.028148] zd1211rw 1-3:1.0: zd_op_start: failed to set radio on

Adding a 10 milliseconds delay between the call to set_mc_hash() and
zd_chip_switch_radio_on() allows successful interface bringups in all
cases and matches what the vendor driver did.

9926a67557 carl9170: fix frame delivery if sta is in powersave mode
Nicolas Cavallari discovered that carl9170 has some
serious problems delivering data to sleeping stations.

It turns out that the driver was not honoring two
important flags (IEEE80211_TX_CTL_POLL_RESPONSE and
IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on
frames that should be sent although the receiving
station is still in powersave mode.

992d52529d carl9170: Fix memory accounting when sta is in power-save mode.
On Access Point mode, when transmitting a packet, if the destination
station is in powersave mode, we abort transmitting the packet to the
device queue, but we do not reclaim the allocated memory.  Given enough
packets, we can go in a state where there is no packet on the device
queue, but we think the device has no memory left, so no packet gets
transmitted, connections breaks and the AP stops working.

This undo the allocation done in the TX path when the station is in
power-save mode.

6459f9871a iwlwifi: rename iwl_remove to iwl_op_mode_dvm_stop
iwl_remove stops the wifi flows, so rename.
Moreover, we can possibly stop the wifi flows even if the driver
is statically compiled in the kernel, so remove the __devexit pragma.

5c58edc63e iwlwifi: introducing the drv object's flows
Fetch the fw and spawn the op_mode. The op_mode that we need
to fetch is determined from the fw file.
Since the fw is fetched very early in the init flow, we can
determine what op_mode to spawn.

a78be210d5 iwlwifi: move uCode flags handling to op_mode
The uCode flags modification is op_mode dependent
since the P2P config is an op-mode config.

This also fixes P2P enabling: due to the uCode
loading code shuffle moving the SKU check before
the EEPROM was read it was always false and would
always disable PAN/P2P.

e211b2427a iwlwifi: move content of iwl_probe to post fetch_fw
This will allow to have different behavior depending on the fw.
Different fw APIs require completely different implementation
of the mac80211 APIs. Each of these implementations is called an
op_mode.

The current op_mode is called DVM which states for dual virtual MAC.

Dumping the RSSI information in the middle of error
statistics is a bit misleading. Move them to the end.

6bcf6f647b ath9k: Merge wiphy and misc debugfs files
This patch merges the 'wiphy' and 'misc' debugfs files
and consolidates the information.

Information about the current channel and other HT parameters
can be obtained from both mac80211 and iw. Remove such
redundant data.

The reset statistics have been removed, they will be re-added in
a subsequent patch (in a new debugfs file).
