From 391e53e33f0028f52ce5eedee1026830571f0d76 Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Fri, 2 Nov 2012 13:27:49 +0100 Subject: [PATCH] mac80211: implement set_mcast_rate() callback This new callback can be used to tune the rate to be used to send multicast frames. In the current state the multicast rate can be specified on IBSS/MESH joining only. This makes it impossible to select a custom multicast rate when then join command is sent by an external program (e.g. wpa_supplicant) Signed-off-by: Antonio Quartulli Signed-off-by: Johannes Berg --- net/mac80211/cfg.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/net/mac80211/cfg.c b/net/mac80211/cfg.c index eebb70b0aa11..80e0618b25ba 100644 --- a/net/mac80211/cfg.c +++ b/net/mac80211/cfg.c @@ -1954,6 +1954,16 @@ static int ieee80211_leave_ibss(struct wiphy *wiphy, struct net_device *dev) return ieee80211_ibss_leave(IEEE80211_DEV_TO_SUB_IF(dev)); } +static int ieee80211_set_mcast_rate(struct wiphy *wiphy, struct net_device *dev, + int rate[IEEE80211_NUM_BANDS]) +{ + struct ieee80211_sub_if_data *sdata = IEEE80211_DEV_TO_SUB_IF(dev); + + memcpy(sdata->vif.bss_conf.mcast_rate, rate, sizeof(rate)); + + return 0; +} + static int ieee80211_set_wiphy_params(struct wiphy *wiphy, u32 changed) { struct ieee80211_local *local = wiphy_priv(wiphy); @@ -3180,6 +3190,7 @@ struct cfg80211_ops mac80211_config_ops = { .disassoc = ieee80211_disassoc, .join_ibss = ieee80211_join_ibss, .leave_ibss = ieee80211_leave_ibss, + .set_mcast_rate = ieee80211_set_mcast_rate, .set_wiphy_params = ieee80211_set_wiphy_params, .set_tx_power = ieee80211_set_tx_power, .get_tx_power = ieee80211_get_tx_power,
