I also want a XDP/eBPF hook placed at TX DMA completion time, or when the page is recycled back to the page-pool. This will allow innovating more advanced DDoS filter solutions, as this creates a feed

Many NICs today does VLAN acceleration by delivering the VLAN TCI in the RX descriptor, and stripping/starting the packet-data after the VLAN header. For XDP this special case handling for VLANs is an
