This +disallows an early switch to the other channel. + +Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> +--- + +--- a/drivers/net/wireless/ath/ath9k/ath9k.h ++++ b/drivers/net/wireless/ath/ath9k/ath9k.h +@@ -362,7 +362,7 @@ enum ath_chanctx_event { + ATH_CHANCTX_EVENT_BEACON_SENT, + ATH_CHANCTX_EVENT_TSF_TIMER, + ATH_CHANCTX_EVENT_BEACON_RECEIVED, +- ATH_CHANCTX_EVENT_ASSOC, ++ ATH_CHANCTX_EVENT_AUTHORIZED, + ATH_CHANCTX_EVENT_SWITCH, + ATH_CHANCTX_EVENT_ASSIGN, + ATH_CHANCTX_EVENT_UNASSIGN, +--- a/drivers/net/wireless/ath/ath9k/channel.c ++++ b/drivers/net/wireless/ath/ath9k/channel.c +@@ -171,7 +171,7 @@ static const char *chanctx_event_string( + case_rtn_string(ATH_CHANCTX_EVENT_BEACON_SENT); + case_rtn_string(ATH_CHANCTX_EVENT_TSF_TIMER); + case_rtn_string(ATH_CHANCTX_EVENT_BEACON_RECEIVED); +- case_rtn_string(ATH_CHANCTX_EVENT_ASSOC); ++ case_rtn_string(ATH_CHANCTX_EVENT_AUTHORIZED); + case_rtn_string(ATH_CHANCTX_EVENT_SWITCH); + case_rtn_string(ATH_CHANCTX_EVENT_ASSIGN); + case_rtn_string(ATH_CHANCTX_EVENT_UNASSIGN); +@@ -510,7 +510,7 @@ void ath_chanctx_event(struct ath_softc + + ath_chanctx_setup_timer(sc, tsf_time); + break; +- case ATH_CHANCTX_EVENT_ASSOC: ++ case ATH_CHANCTX_EVENT_AUTHORIZED: + if (sc->sched.state != ATH_CHANCTX_STATE_FORCE_ACTIVE || + avp->chanctx != sc->cur_chan) + break; +--- a/drivers/net/wireless/ath/ath9k/main.c ++++ b/drivers/net/wireless/ath/ath9k/main.c +@@ -1569,6 +1569,13 @@ static int ath9k_sta_state(struct ieee80 + "Remove station: %pM\n", sta->addr); + } + ++ if (ath9k_is_chanctx_enabled()) { ++ if (old_state == IEEE80211_STA_ASSOC && ++ new_state == IEEE80211_STA_AUTHORIZED) ++ ath_chanctx_event(sc, vif, ++ ATH_CHANCTX_EVENT_AUTHORIZED); ++ } ++ + return ret; + } + +@@ -1761,12 +1768,6 @@ static void ath9k_bss_info_changed(struc + avp->assoc = bss_conf->assoc; + + ath9k_calculate_summary_state(sc, avp->chanctx); +- +- if (ath9k_is_chanctx_enabled()) { +- if (bss_conf->assoc) +- ath_chanctx_event(sc, vif, +- ATH_CHANCTX_EVENT_ASSOC); +- } + } + + if (changed & BSS_CHANGED_IBSS) { |
