* rt2x00: Fix rt2800 USB TX Path DMA issueRA-Jay Hung2010-11-17
| | | | | | | | | | | | | | | rt2800usb chips need to add 1~3 bytes zero padding after each 802.11 header & payload, and at the end need to add 4 bytes zero padding whether doing TX bulk aggregation or not, TXINFO_W0_USB_DMA_TX_PKT_LEN in TXINFO must include 1-3 bytes padding after 802.11 header & payload but do not include 4 bytes end zero padding. In rt2800usb_get_tx_data_len do not consider multiple of the USB packet size case, sometimes this will cause USB DMA problem.

* rt2x00: Remove RT30XX Kconfig variables.Gertjan van Wingerde2010-11-17
| | | | | | | | | | | | | Enabling of RT30xx devices via Kconfig variables was introduced when these devices weren't properly supported yet. Now that that they are properly supported and functional, we can remove these Kconfig variables for RT30xx devices and simply enable them whenever rt2800pci and/or rt2800usb is enabled.

* rt2x00: Clean up Kconfig for RT2800 devices.Gertjan van Wingerde2010-11-17
| | | | | | | | | | | | | | General clean up of the Kconfig part for RT28XX devices. Also remove the indications of non functional support for rt27xx/rt28xx/rt30xx devices, as this is no longer true. They just work fine. Finally, remove the experimental indications for rt27xx/rt28xx/rt30xx devices as that is no longer true. Keep the experimental indications for rt33xx/rt35xx devices, though.

| | | | | | | | | | | | TX underruns were noticed when RTS/CTS preceded aggregates. This issue was noticed in ar93xx family of chipsets only. The workaround involves padding the RTS or CTS length up to the min packet length of 256 bytes required by the hardware by adding delimiters to the fist descriptor of the aggregate.

| | | | | | | | | | | | | | | | BCM4320a devices do not return bss for currently connected AP in bss-list, althought this is required by NDIS specs. Missing bss leads to warning at net/wireless/sme.c:__cfg80211_connect_result(), WARN_ON(!bss). Workaround this by crafting bss manually with information we can read from device. Workaround is only used when device bss-list does not return current bss, and so is only used with BCM4320a devices and not newer BCM4320b ones. Fixes bug #20152.

| | | | | | | | | | | Introduce a firmware loading state machine to manage the process of loading firmware asynchronously and completing initialization upon success.

* mwl8k: add API version checking for AP firmwareBrian Cavagnolo2010-11-16
| | | | | | | | | | | | The AP firmware specifies an API version in the GET_HW_SPEC command response. Currently, the driver only supports AP firmware for the 8366, and only supports API v1. In the future, if higher API version firmwares emerge (possibly for different chips), different ops can be selected based on the reported API version.

* mwl8k: choose proper firmware image as directed by userBrian Cavagnolo2010-11-16
| | | | | | | | | | | | | | | | | | | | | The mwl8k can operate in AP or STA mode, depending on the firmware image that is loaded. By default, STA firmware is loaded. Allow the user to override this default mode at module load time. This saves an unnecessary firmware reload for users only interested in AP mode. Also, the firmware image can be swapped to meet the user's add_interface request. For example, suppose the STA firmware is loaded, no STA interface has been added, and the user adds an AP interface. In this case, the AP firmware will be loaded to meet the request.

* libertas: EHS_REMOVE_WAKEUP is not always supportedDeepak Saxena2010-11-16
| | | | | | | | | | | | | | | | Certain firmware versions, particularly the 8388 found on the XO-1, do not support the EHS_REMOVE_WAKEUP command that is used to disable WOL.

| | | | | | | | | | | | | | | | | This hunk added by commit 66fceb69b72f seems erroneous. We don't want to prevent suspend of the whole system if no wakeup params are set. In the case of the usb8388 we do want to keep the card powered up even if there are no wakeup params. This is because it will continue acting as a mesh node. If the mesh is disabled, it would indeed make more sense to power down the card during suspend, as the equivalent hunk does for the SD interface. But that's a separate task; for now just restore the previous behaviour. Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
