2009-07-10iwmc3200wifi: simplify calibration mapZhu Yi
The patch simplifies calibration map by combining the init_calib_map and periodic_calib_map into one calib_map in struct iwm_conf. Now the initial calibration map is stored in the lower 16 bits of calib_map and the periodic calibration map is stored in the higher 16 bits.

2009-07-10ath9k: differentiate quality reporting between legacy and HT configurationsLuis R. Rodriguez
We were not differentiating quality between legacy and HT configurations. We change this to consider the differences. New theory for reporting quality: At a hardware RSSI of 45 you will be able to use MCS 7 reliably. At a hardware RSSI of 45 you will be able to use MCS 15 reliably. At a hardware RSSI of 35 you should be able use 54 Mbps reliably. MCS 7 is the highets MCS index usable by a 1-stream device. MCS 15 is the highest MCS index usable by a 2-stream device. All ath9k devices are either 1-stream or 2-stream. How many bars you see is derived from the qual reporting. A more elaborate scheme can be used here but it requires tables of SNR/throughput for each possible mode used. For the MCS table you can refer to the wireless wiki: http://wireless.kernel.org/en/developers/Documentation/ieee80211/802.11n This should fix this bug report: http://bugzilla.kernel.org/show_bug.cgi?id=13537 Cc: Janath.Peiris@atheros.com Cc: Matt.Smith@atheros.com Signed-off-by: Luis R.

2009-07-10libertas: fix card cleanup order in SDIO driverAndrey Yurovsky
The SDIO driver sets the surpriseremoved flag before calling lbs_remove_card. With IEEE PS enabled, lbs_remove_card must issue a command to exit IEEE PS mode, however with that flag set the command path is blocked and the card is never taken out of IEEE PS mode. This step is required to ensure that the driver can be reloaded. This patch moves the setting of surpriseremoved after lbs_remove_card is called. Tested with V9 firmware by ensuring that IEEE PS is disabled when the driver is removed. Reloading the driver is not fully tested due to a separate issue with module reload in the SDIO driver, however this patch at least leaves the card in a better state when we bring the driver down.

2009-07-10libertas: correct card cleanup order in SPI driverAndrey Yurovsky
The SPI driver does a couple of card cleanup steps in the wrong order on module removal. If IEEE PS is enabled, this results in the card being left in IEEE PS mode and subsequent failures to reload the module. The problem is that the surpriseremoved flag is set before calling lbs_remove_card, but that function needs to issue a command to exit IEEE PS mode (the flag blocks the command path). In addition, lbs_stop_card should be called first because it clears out any pending commands. Tested on a GSPI device with V9 firmware by confirming that we can reload the module with or without IEEE PS enabled. Also fix a warning from the wrong uint format in a printk. V2: use z modifier, thanks Sebastian. Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-07-10libertas: copy WPA keys to priv when associatingAndrey Yurovsky
Libertas currently maintains a copy of the WPA unicast and group keys when using WPA or WPA2. This copy is checked when deciding whether or not to return to sleep in IEEE PS mode but the actual copying back to priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one issues commands that require temporarily keeping the device awake. This patch introduces the omitted copy-back of the keys so that IEEE PS functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for clearing up the issue. V2: fix typo. Also, this has been tested on GSPI and SDIO with V9 firmware. Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2009-07-10cfg80211: implement iwpowerJohannes Berg

2009-07-10cfg80211: introduce nl80211 testmode commandJohannes Berg
This introduces a new NL80211_CMD_TESTMODE for testing and calibration use with nl80211. There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

2009-07-10orinoco: initiate cfg80211 conversionDavid Kilroy
Initialise and register a wiphy. Store the orinoco_private structure in the new wiphy, and use the net_device private area to store the wireless_dev. This results in a change to the way we navigate from a net_device to the driver private orinoco_private, which we encapsulate in the inline function ndev_priv. Most of the remaining calls to netdev_priv are thus replaced by ndev_priv. We can immediately rely on cfg80211 to handle SIOCGIWNAME, so orinoco_ioctl_getname is removed.
