2010-11-16mac80211: Add antenna configurationBruno Randolf4-0/+94
Allow antenna configuration by calling driver's function for it. We disallow antenna configuration if the wiphy is already running, mainly to make life easier for 802.11n drivers which need to recalculate HT capabilites.

2010-11-16cfg80211: Add nl80211 antenna configurationBruno Randolf3-1/+58
Allow setting of TX and RX antennas configuration via nl80211. The antenna configuration is defined as a bitmap of allowed antennas to use. This API can be used to mask out antennas which are not attached or should not be used for other reasons like regulatory concerns or special setups. Separate bitmaps are used for RX and TX to allow configuring different antennas for receiving and transmitting. Each bitmap is 32 bit long, each bit representing one antenna, starting with antenna 1 at the first bit. If an antenna bit is set, this means the driver is allowed to use this antenna for RX or TX respectively; if the bit is not set the hardware is not allowed to use this antenna. Using bitmaps has the benefit of allowing for a flexible configuration interface which can support many different configurations and which can be used for 802.11n as well as non-802.11n devices. Instead of relying on some hardware specific assumptions, drivers can use this information to know which antennas are actually attached to the system and derive their capabilities based on that. 802.11n devices should enable or disable chains, based on which antennas are present (If all antennas belonging to a particular chain are disabled, the entire chain should be disabled). HT capabilities (like STBC, TX Beamforming, Antenna selection) should be calculated based on the available chains after applying the antenna masks. Should a 802.11n device have diversity antennas attached to one of their chains, diversity can be enabled or disabled based on the antenna information. Non-802.11n drivers can use the antenna masks to select RX and TX antennas and to enable or disable antenna diversity. While covering chainmasks for 802.11n and the standard "legacy" modes "fixed antenna 1", "fixed antenna 2" and "diversity" this API also allows more rare, but useful configurations as follows: 1) Send on antenna 1, receive on antenna 2 (or vice versa). This can be used to have a low gain antenna for TX in order to keep within the regulatory constraints and a high gain antenna for RX in order to receive weaker signals ("speak softly, but listen harder"). This can be useful for building long-shot outdoor links. Another usage of this setup is having a low-noise pre-amplifier on antenna 1 and a power amplifier on the other antenna. This way transmit noise is mostly kept out of the low noise receive channel. (This would be bitmaps: tx 1 rx 2). 2) Another similar setup is: Use RX diversity on both antennas, but always send on antenna 1. Again that would allow us to benefit from a higher gain RX antenna, while staying within the legal limits. (This would be: tx 0 rx 3). 3) And finally there can be special experimental setups in research and development even with pre 802.11n hardware where more than 2 antennas are available. It's good to keep the API simple, yet flexible. Signed-off-by: Bruno Randolf <br1@einfach.org> -- v7: Made bitmasks 32 bit wide and rebased to latest wireless-testing. Signed-off-by: John W.

2010-11-16rndis_wlan: workaround device not returning bss for currently connected APJussi Kivilinna1-9/+121
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.

2010-11-16mwl8k: choose proper firmware image as directed by userBrian Cavagnolo1-12/+66
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.

2010-11-16libertas: don't block usb8388 suspend if no wakeup conditions are setDaniel Drake1-6/+0
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.
