This patch was tested on AR9380-AL1A cards. Signed-off-by: Jan Kaisrlik Cc: Michal Sojka --- changes: * OCB mode is treated like AP mode rather than like ad hoc mode. Btw. I couldn't find any reasonable documentation about AR_STA_ID1_ADHOC AR_STA_ID1_STA_AP bits. In my tests, OCB communication works in both modes, but I'd like to understand the difference. Can somebody point me to some information about these bits? drivers/net/wireless/ath/ath9k/ath9k.h | 1 + drivers/net/wireless/ath/ath9k/debug.c | 4 ++-- drivers/net/wireless/ath/ath9k/htc_drv_init.c | 3 ++- drivers/net/wireless/ath/ath9k/hw.c | 1 + drivers/net/wireless/ath/ath9k/init.c | 3 ++- drivers/net/wireless/ath/ath9k/main.c | 8 +++++++- drivers/net/wireless/ath/ath9k/recv.c | 2 +- 7 files changed, 16 insertions(+), 6 deletions(-) diff --git a/drivers/net/wireless/ath/ath9k/ath9k.h b/drivers/net/wireless/ath/ath9k/ath9k.h index c85c479..b42f4a9 100644 --- a/drivers/net/wireless/ath/ath9k/ath9k.h +++ b/drivers/net/wireless/ath/ath9k/ath9k.h @@ -635,6 +635,7 @@ struct ath9k_vif_iter_data { int nstations; /* number of station vifs */ int nwds; /* number of WDS vifs */ int nadhocs; /* number of adhoc vifs */ + int nocbs; /* number of OCB vifs */ struct ieee80211_vif *primary_sta; }; diff --git a/drivers/net/wireless/ath/ath9k/debug.c b/drivers/net/wireless/ath/ath9k/debug.c index da32c8f..6de64cf 100644 --- a/drivers/net/wireless/ath/ath9k/debug.c +++ b/drivers/net/wireless/ath/ath9k/debug.c @@ -741,8 +741,8 @@ static int read_file_misc(struct seq_file *file, void *data) i++, (int)(ctx->assigned), iter_data.naps, iter_data.nstations, iter_data.nmeshes, iter_data.nwds); - seq_printf(file, " ADHOC: %i TOTAL: %hi BEACON-VIF: %hi\n", - iter_data.nadhocs, sc->cur_chan->nvifs, + seq_printf(file, " ADHOC: %i OCB: %i TOTAL: %hi BEACON-VIF: %hi\n", + iter_data.nadhocs, iter_data.nocbs, sc->cur_chan->nvifs, sc->nbcnvifs); } diff --git a/drivers/net/wireless/ath/ath9k/htc_drv_init.c b/drivers/net/wireless/ath/ath9k/htc_drv_init.c index 1e84882..5e53040 100644 --- a/drivers/net/wireless/ath/ath9k/htc_drv_init.c +++ b/drivers/net/wireless/ath/ath9k/htc_drv_init.c @@ -736,7 +736,8 @@ static void ath9k_set_hw_capab(struct ath9k_htc_priv *priv, BIT(NL80211_IFTYPE_AP) | BIT(NL80211_IFTYPE_P2P_GO) | BIT(NL80211_IFTYPE_P2P_CLIENT) | - BIT(NL80211_IFTYPE_MESH_POINT); + BIT(NL80211_IFTYPE_MESH_POINT) | + BIT(NL80211_IFTYPE_OCB); hw->wiphy->iface_combinations = &if_comb; hw->wiphy->n_iface_combinations = 1; diff --git a/drivers/net/wireless/ath/ath9k/hw.c b/drivers/net/wireless/ath/ath9k/hw.c index 1dd0339..bdfff46 100644 --- a/drivers/net/wireless/ath/ath9k/hw.c +++ b/drivers/net/wireless/ath/ath9k/hw.c @@ -1241,6 +1241,7 @@ static void ath9k_hw_set_operating_mode(struct ath_hw *ah, int opmode) break; } /* fall through */ + case NL80211_IFTYPE_OCB: case NL80211_IFTYPE_MESH_POINT: case NL80211_IFTYPE_AP: set |= AR_STA_ID1_STA_AP; diff --git a/drivers/net/wireless/ath/ath9k/init.c b/drivers/net/wireless/ath/ath9k/init.c index 57f95f2..5d532c7 100644 --- a/drivers/net/wireless/ath/ath9k/init.c +++ b/drivers/net/wireless/ath/ath9k/init.c @@ -855,7 +855,8 @@ static void ath9k_set_hw_capab(struct ath_softc *sc, struct ieee80211_hw *hw) BIT(NL80211_IFTYPE_STATION) | BIT(NL80211_IFTYPE_ADHOC) | BIT(NL80211_IFTYPE_MESH_POINT) | - BIT(NL80211_IFTYPE_WDS); + BIT(NL80211_IFTYPE_WDS) | + BIT(NL80211_IFTYPE_OCB); if (ath9k_is_chanctx_enabled()) hw->wiphy->interface_modes |= diff --git a/drivers/net/wireless/ath/ath9k/main.c b/drivers/net/wireless/ath/ath9k/main.c index c27143b..56abb9d 100644 --- a/drivers/net/wireless/ath/ath9k/main.c +++ b/drivers/net/wireless/ath/ath9k/main.c @@ -938,6 +938,9 @@ static void ath9k_vif_iter(struct ath9k_vif_iter_data *iter_data, if (avp->assoc && !iter_data->primary_sta) iter_data->primary_sta = vif; break; + case NL80211_IFTYPE_OCB: + iter_data->nocbs++; + break; case NL80211_IFTYPE_ADHOC: iter_data->nadhocs++; if (vif->bss_conf.enable_beacon) @@ -1111,6 +1114,8 @@ void ath9k_calculate_summary_state(struct ath_softc *sc, if (iter_data.nmeshes) ah->opmode = NL80211_IFTYPE_MESH_POINT; + else if (iter_data.nocbs) + ah->opmode = NL80211_IFTYPE_OCB; else if (iter_data.nwds) ah->opmode = NL80211_IFTYPE_AP; else if (iter_data.nadhocs) @@ -1760,7 +1765,8 @@ static void ath9k_bss_info_changed(struct ieee80211_hw *hw, ath9k_calculate_summary_state(sc, avp->chanctx); } - if (changed & BSS_CHANGED_IBSS) { + if ((changed & BSS_CHANGED_IBSS) || + (changed & BSS_CHANGED_OCB)) { memcpy(common->curbssid, bss_conf->bssid, ETH_ALEN); common->curaid = bss_conf->aid; ath9k_hw_write_associd(sc->sc_ah); diff --git a/drivers/net/wireless/ath/ath9k/recv.c b/drivers/net/wireless/ath/ath9k/recv.c index d3189da..994daf6 100644 --- a/drivers/net/wireless/ath/ath9k/recv.c +++ b/drivers/net/wireless/ath/ath9k/recv.c @@ -403,7 +403,7 @@ u32 ath_calcrxfilter(struct ath_softc *sc) (sc->cur_chan->nvifs <= 1) && !(sc->cur_chan->rxfilter & FIF_BCN_PRBRESP_PROMISC)) rfilt |= ATH9K_RX_FILTER_MYBEACON; - else + else if (sc->sc_ah->opmode != NL80211_IFTYPE_OCB) rfilt |= ATH9K_RX_FILTER_BEACON; if ((sc->sc_ah->opmode == NL80211_IFTYPE_AP) || -- 2.1.4
