This is needed for drivers that need to know when the interface is IF_OPER_UP (e.g. wl12xx), and block notifiers can't be used (e.g. because the interface is already IF_OPER_UP, like after resuming from suspend) Signed-off-by: Eliad Peller --- include/net/mac80211.h | 10 ++++++++++ net/mac80211/mlme.c | 7 +++++++ 2 files changed, 17 insertions(+), 0 deletions(-) diff --git a/include/net/mac80211.h b/include/net/mac80211.h index 8c7189c..d19e325 100644 --- a/include/net/mac80211.h +++ b/include/net/mac80211.h @@ -2915,6 +2915,16 @@ void ieee80211_cqm_rssi_notify(struct ieee80211_vif *vif, gfp_t gfp); /** + * ieee80211_get_operstate - get the operstate of the vif + * + * @vif: &struct ieee80211_vif pointer from the add_interface callback. + * + * The driver might need to know the operstate of the net_device + * (specifically, whether the link is IF_OPER_UP after resume) + */ +unsigned char ieee80211_get_operstate(struct ieee80211_vif *vif); + +/** * ieee80211_chswitch_done - Complete channel switch process * @vif: &struct ieee80211_vif pointer from the add_interface callback. * @success: make the channel switch successful or not diff --git a/net/mac80211/mlme.c b/net/mac80211/mlme.c index 4f6b267..c81a99d 100644 --- a/net/mac80211/mlme.c +++ b/net/mac80211/mlme.c @@ -2651,3 +2651,10 @@ void ieee80211_cqm_rssi_notify(struct ieee80211_vif *vif, cfg80211_cqm_rssi_notify(sdata->dev, rssi_event, gfp); } EXPORT_SYMBOL(ieee80211_cqm_rssi_notify); + +unsigned char ieee80211_get_operstate(struct ieee80211_vif *vif) +{ + struct ieee80211_sub_if_data *sdata = vif_to_sdata(vif); + return sdata->dev->operstate; +} +EXPORT_SYMBOL(ieee80211_get_operstate); -- 1.7.0.4
