mac80211 converts 802.3 multicast packets to 802.11 format before driver TX, even when Ethernet encapsulation offload is enabled. This prevents drivers that support multicast Ethernet encapsulation offload from receiving frames in native 802.3 format. Introduce the IEEE80211_OFFLOAD_ENCAP_MCAST flag to bypass the 802.11 encapsulation step and pass the multicast packet to the driver in 802.3 format. Drivers that support multicast Ethernet encapsulation offload can advertise this flag. Disable multicast encapsulation offload in MLO case for drivers not advertising MLO_MCAST_MULTI_LINK_TX support for AP mode and for 3-address AP_VLAN multicast packets.
