It is +recommended to increase this value from 1 or 6 Mbit/s to something higher +when using a mesh protocol on top which uses the multicast packet loss as +indicator for the link quality. + +This setting was unfortunately not applied for mesh mode. But it would be +beneficial when wpa_supplicant would behave similar to IBSS mode and set +this argument during mesh join like authsae already does. At least it is +helpful for companies/projects which are currently switching to 802.11s +(without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS +because newer drivers seem to support 802.11s but not IBSS anymore. + +Signed-off-by: Sven Eckelmann <sven.eckelmann@openmesh.com> +Tested-by: Simon Wunderlich <simon.wunderlich@openmesh.com> + +--- a/src/drivers/driver.h ++++ b/src/drivers/driver.h +@@ -1426,6 +1426,7 @@ struct wpa_driver_mesh_join_params { + #define WPA_DRIVER_MESH_FLAG_SAE_AUTH 0x00000004 + #define WPA_DRIVER_MESH_FLAG_AMPE 0x00000008 + unsigned int flags; ++ int mcast_rate; + }; + + /** +--- a/src/drivers/driver_nl80211.c ++++ b/src/drivers/driver_nl80211.c +@@ -8997,6 +8997,18 @@ static int nl80211_put_mesh_id(struct nl + } + + ++static int nl80211_put_mcast_rate(struct nl_msg *msg, int mcast_rate) ++{ ++ if (mcast_rate > 0) { ++ wpa_printf(MSG_DEBUG, " * mcast_rate=%.1f", ++ (double)mcast_rate / 10); ++ return nla_put_u32(msg, NL80211_ATTR_MCAST_RATE, mcast_rate); ++ } ++ ++ return 0; ++} ++ ++ + static int nl80211_put_mesh_config(struct nl_msg *msg, + struct wpa_driver_mesh_bss_params *params) + { +@@ -9055,6 +9067,7 @@ static int nl80211_join_mesh(struct i802 + nl80211_put_basic_rates(msg, params->basic_rates) || + nl80211_put_mesh_id(msg, params->meshid, params->meshid_len) || + nl80211_put_beacon_int(msg, params->beacon_int) || ++ nl80211_put_mcast_rate(msg, params->mcast_rate) || + nl80211_put_dtim_period(msg, params->dtim_period)) + goto fail; + +--- a/wpa_supplicant/mesh.c ++++ b/wpa_supplicant/mesh.c +@@ -379,6 +379,7 @@ int wpa_supplicant_join_mesh(struct wpa_ + os_memset(¶ms, 0, sizeof(params)); + params.meshid = ssid->ssid; + params.meshid_len = ssid->ssid_len; ++ params.mcast_rate = ssid->mcast_rate; + ibss_mesh_setup_freq(wpa_s, ssid, ¶ms.freq); + wpa_s->mesh_ht_enabled = !!params.freq.ht_enabled; + wpa_s->mesh_vht_enabled = !!params.freq.vht_enabled; |
