The patch should work, but I wonder if we should be fiddling with priv->vif for this, perhaps we should not assume vif to be valid after rtl8187_remove_interface (I don't see problems with current rtl8187/mac80211 code on a quick look, but...) I cleaner solution may be to use a priv->mode like p54. > > Larry > -- []'s Herton -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
