2008-02-29cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg
This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

2008-02-29iwlwifi: A-MPDU Tx activation by load measuresRon Rindjunsky
This patch gives a heuristic for activation of the A-MPDU Tx. As the rate scaling is rate aware, it now also measures estimated load, and sends A-MPDU activation after a threshold has been met.

2008-02-29mac80211: A-MPDU Tx add session's and low level driver's APIRon Rindjunsky
This patch adds the API for 3 stages in A-MPDU Tx session flow: - request mac80211 to start/stop A-MPDU Tx session for specific TID. such a request should be issued by a load aware element, either mac80211 itself or external element. - requests by mac80211 to low-level driver to start/stop Tx aggregation. notice that low level driver responds now with Starting Sequence Number. - async feedback by low-level to mac80211 to inform that HW is ready for next A-MPDU Tx state. Changes in API to Rx A-MPDU were also made, reflected in iwlwifi changes as well. Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28iwlwifi: delay firmware loading from pci_probe to network interface openZhu Yi
This patch moves the firmware loading (read firmware from disk and load it into the device SRAM) from pci_probe time to the first network interface open time. There are two reasons for doing this: 1. To support kernel buildin iwlwifi drivers. Because kernel initializes network devices subsystem before hard disk and SATA subsystem, it is impossible to get the firmware image from hard disk in the PCI probe handler. Thus delaying the firmware loading into the network interface open time is the way to go. Note, we only read the firmware image from hard disk the first time the interface is open. After this is succeeded, we cache the firmware image into the host memory. This is a performance gain when user open and close the interface multiple times and is necessary for device suspend and resume. 2. For better power saving. When the iwlwifi modules are loaded (or buildin the kernel) but the wireless network interface is not being used, it is a good practice the wireless device consumes as less power as possible. Unloading the firmware from the wireless device and unregister the driver's interrupt handler in the network interface close handler provides users a way to achieve this. User space network configuration tools (i.e NetworkManager) can also contribute here when it detects a wired cable is connected and close the wireless interface automatically. This patch also includes the pci_save/restore_state() fixed by Ian Schram upon the first version.

2008-01-28mac80211: add unified BSS configurationJohannes Berg
This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.
