package/kernel/mac80211/patches/901-wlcore-memset-wl--rx_filter_enabled-to-zero-after-recovery.patch

   1 zero rx_filter_enabled array after recovery to avoid
   2 cases were the driver will keep trying to clear a
   3 filter which is not configured in FW.
   4
   5 Such case will cause consecutive recoveries due to
   6 command execution failures.
   7
   8 While on it, convert rx_filter_enabled to bitmap,
   9 to save some memory and make sparse happy (it
  10 doesn't like sizeof(bool array)).
