Hi, The commit "mac80211: stop tx before doing hw config and rate update" (and a later commit fixing it) introduced a queue stop & flush on switching 20/40. I'm working on not calling hw_config() for switching between 20/40 but instead only calling rate_control_rate_update() and ieee80211_bss_info_change_notify() to tell the rate control and driver. If we do that, is it still necessary to stop the queues for it? It seems like it shouldn't. johannes -- 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
