The callback can be used with vif configured as ADHOC or MESH_POINT only. 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 --- net/mac80211/cfg.c | 7 +++++++ net/mac80211/ieee80211_i.h | 3 +++ net/mac80211/util.c | 12 ++++++++++++ 3 files changed, 22 insertions(+) diff --git a/net/mac80211/cfg.c b/net/mac80211/cfg.c index ed27988..21461dc 100644 --- a/net/mac80211/cfg.c +++ b/net/mac80211/cfg.c @@ -1924,6 +1924,12 @@ 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]) +{ + return ieee80211_mcast_rate(IEEE80211_DEV_TO_SUB_IF(dev), rate); +} + static int ieee80211_set_wiphy_params(struct wiphy *wiphy, u32 changed) { struct ieee80211_local *local = wiphy_priv(wiphy); @@ -3123,6 +3129,7 @@ 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, diff --git a/net/mac80211/ieee80211_i.h b/net/mac80211/ieee80211_i.h index 78c4bbb..e3b9eff 100644 --- a/net/mac80211/ieee80211_i.h +++ b/net/mac80211/ieee80211_i.h @@ -1575,6 +1575,9 @@ void ieee80211_vif_release_channel(struct ieee80211_sub_if_data *sdata); void ieee80211_recalc_smps_chanctx(struct ieee80211_local *local, struct ieee80211_chanctx *chanctx); +int ieee80211_mcast_rate(struct ieee80211_sub_if_data *sdata, + int rate[IEEE80211_NUM_BANDS]); + #ifdef CONFIG_MAC80211_NOINLINE #define debug_noinline noinline #else diff --git a/net/mac80211/util.c b/net/mac80211/util.c index 350b7a7..c9f6813 100644 --- a/net/mac80211/util.c +++ b/net/mac80211/util.c @@ -1959,3 +1959,15 @@ u8 ieee80211_mcs_to_chains(const struct ieee80211_mcs_info *mcs) return 2; return 1; } + +int ieee80211_mcast_rate(struct ieee80211_sub_if_data *sdata, + int rate[IEEE80211_NUM_BANDS]) +{ + if (sdata->vif.type != NL80211_IFTYPE_ADHOC && + sdata->vif.type != NL80211_IFTYPE_MESH_POINT) + return -EOPNOTSUPP; + + memcpy(sdata->vif.bss_conf.mcast_rate, &rate, sizeof(rate)); + + return 0; +}
