I'm sorry for my ambiguous representation. Until Revision 257951, work. =46rom r258030 to r258034, doesn't work. If antmask_2stream set to be IWN_ANT_AB, work. After r258035, doesn't work. antmask_2stream =3D IWN_ANT_AB doesn't help. > Ok.

Rivision 258035 changed many lines and if_iwn_chip_cfg.h was created. I faced a trouble about where should I try to change. --=20 Kaho Toshikazu
