package/kernel/mac80211/patches/908-wlcore-wl12xx-wl18xx-configure-iface_combinations-per-hw.patch

   1 Each hw supports a different iface combinations.
   2 Define the supported combinations in each driver,
   3 and save it in wl->iface_combinations.
   4
   5 Since each driver defines its own combinations now,
   6 it can also define its max supported channels, so
   7 we no longer need to save and set it explicitly
   8 in wlcore.
   9
  10 Update wl18xx interface combinations to allow
  11 multiple APs.
