One thing I forgot, do we need a special iwlwifi flag to turn this off? Or can iwlwifi be programmed to let the host handle this (*), which might be beneficial for interoperability and uniformity purposes? johannes (*) it would need to implement a beacon filter that passes up only modified beacons (where modified doesn't take into account the TIM IE except for the own AID/bcast bits), and turns off the null function stuff in firmware --=-Pq+2VDmMZgKdRPAd2Czz Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJM9L9AAoJEKVg1VMiehFYJcAQAKElOSCtVFHtYI//7j8lHF48 Pw7Pw7mZIXluOhff8vULmLlSOTmwTHP8ipYYPGWFIitcv8GrCMBdNJcEorJhebAK SLX5SMi604U66QnwpcfGnAqTi/9R4VdAnENm4RKI5fIUV5l+rdAGTAWdVoK+uAdJ Cgi/5A4h0C6eur9x35ntqdOvxWUwkEFuK2ZiHERdMS7znS/ntJyiaucJCfgVlQWj S8AER+ZjLs1NshoR9Rk8wlHUyceCu4tIbPG5mErSyGlHGEFxCFEiXvyezbKkkMmD kGJ3BOjbBf9R19pOfkJefEl7lZ0PlPywOJk9/UJ0BT/b7uMlbMEPrw5kCINVGIr9 HeYqlTMZy4hHv5kEYkhj9OqbCzRywY4Xl3TwnVLcUVwGTYfOx4Gk7C6uRMoBxeQb MSgjaDn06UqeuxraQ0u6H6mY0BcWt6tzQp5BMmjXHi38RHhcEtGE3H6IGfe0CjY7 tAI+7jgBn5adwO6qt6rUnwPjnl+zDI/DcIqJtRCxYTLGDkrcESy/YieR/cBYB7HC 1gjAauk/6wW1f3mBASs0LkFEv2ovk/PnQFW7yXo8P46Pvr8W3C4u5Ts8r/lcA/n7 sbKmykYRxiaQfaWTmigtPM25KFOCl+4X7TKeo1wKtCNfli2Lrw9mhlKLsLW+i+I+ DgIIwE4l7NSnCtl2+Wiq =iI6o -----END PGP SIGNATURE----- --=-Pq+2VDmMZgKdRPAd2Czz--
