* mac80211: remove struct ieee80211_if_init_confJohannes Berg2009-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All its members (vif, mac_addr, type) are now available in the vif struct directly, so we can pass that instead of the conf struct.

* mac80211: allow configure_filter callback to sleepJohannes Berg2009-08-20
| | | | | | | | | | | | | | | | | | | | | Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

* adm8211: remove uneeded code during suspend/resumeLuis R. Rodriguez2009-07-24
| | | | | | | | | | mac80211 drivers do not need to stop the software queues or call their own stop() callback upon suspend as we do it for drivers.

* mac80211: push rx status into skb->cbJohannes Berg2009-07-10
| | | | | | | | | | | | | | | Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: unify config_interface and bss_info_changedJohannes Berg2009-05-06
| | | | | | | | | | | The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

* mac80211/drivers: rewrite the rate control APIJohannes Berg2008-10-31
| | | | | | | | | | | | So after the previous changes we were still unhappy with how convoluted the API is and decided to make things simpler for everybody. This completely changes the rate control API, now taking into account 802.11n with MCS rates and more control, most drivers don't support that though.

| | | | | | | | | | | | | | This makes mac80211 notify the driver which configuration actually changed, e.g. channel etc. No driver changes, this is just plumbing, driver authors are expected to act on this if they want to.

* cfg80211: keep track of supported interface modesLuis R. Rodriguez2008-09-05
| | | | | | | | | | | | | | | | It is obviously good for userspace to know up front which interface modes a given piece of hardware might support (even if adding such an interface might fail later because of concurrency issues), so let's make cfg80211 aware of that. For good measure, disallow adding interfaces in all other modes so drivers don't forget to announce support for one mode when they add it.

* mac80211: use hardware flags for signal/noise unitsBruno Randolf2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: dont use interface indices in driversJohannes Berg2008-01-28
| | | | | | | | | | | | | | | | This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* [PATCH] mac80211: revamp interface and filter configurationJohannes Berg2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
