=46ound the problem, that's my fault at merge of omap and wireless-test=
ing=20
trees:
p54_configure_filter that I tested with has the following code:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 *total_flags &=3D FIF_PROMISC_IN_BSS |
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 FIF_OTHER_BSS |
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 (*total_flags & FIF_PROMISC_IN_BSS) ?
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 FIF_FCSFAIL : 0;
which does not what it is intended to. '|' operator has higher preceden=
ce=20
than '? :'
thus it is equivalent to *total_flags &=3D FIF_FCSFAIL; which never yie=
lds=20
neither
=46IF_PROMISC_IN_BSS nor FIF_OTHER_BSS.
Current wireless-testing head has=20
=C2=A0 =C2=A0 =C2=A0 =C2=A0 *total_flags &=3D FIF_PROMISC_IN_BSS |
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 FIF_OTHER_BSS;
at this place, which work fine.
--=20
Thanks.
