This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers.

[PATCH] mac80211: revamp interface and filter configuration 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. Driver modifications by Johannes Berg (b43 & iwlwifi), Michael Wu (rtl8187, adm8211, and p54), Larry Finger (b43legacy), and Ivo van Doorn (rt2x00).

mac80211: use hardware flags for signal/noise units 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.

[PATCH] mac80211: revamp interface and filter configuration 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.

rt2x00: Add per-interface structure Rework the interface handling. Delete the interface structure and replace it with a per-interface structure. This changes the way rt2x00 handles the active interface drastically. Copy ieee80211_bss_conf to the this rt2x00_intf structure during the bss_info_changed() callback function. This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers. While we are cleaning up the interface configuration anyway, we might as well clean up the configuration handler as well. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
