[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.
