Hi, this series tries to optimize multicast delivery on access points with AP_VLAN interfaces.
My setup is as follows: hostapd creates one AP_VLAN interface per station (per_sta_vif=1), which enables bridge igmp snooping to decide which stations need to receive a multicast packet. This series then - avoids multicast packets by tracking the number of authenticated stations per interface more accurately and drops packets if there is no receiver connected, - converts multicast packets to unicast packets for the most common protocols, so they get delivered faster and more reliable. Additionally, waking up non-receivers in other VLANs is avoided. - speeds up station lookup if there is only one authenticated station assigned to the AP_VLAN interface. Sincerely, M.
