You must enable it for every interface which should participate in - the XDP forwarding. - - XDP is an eBPF based high performance data path merged in the Linux kernel - since version 4.8. The idea behind XDP is to add an early hook in the RX path - of the kernel, and let a user supplied eBPF program decide the fate of the - packet. The hook is placed in the NIC driver just after the interrupt - processing, and before any memory allocation needed by the network stack - itself, because memory allocation can be an expensive operation. - - .. warning:: This is highly experimental! - - .. note:: Enabling this feature will break any form of NAT or Firewalling on - this interface, as XDP is handled way earlier in the driver then iptables/ - nftables. - - Enabling this feature will only load the XDP router code as described here: - https://blog.apnic.net/2020/04/30/how-to-build-an-xdp-based-bgp-peering-router/ - - Example: - - .. code-block:: none - - set interfaces {{ var0 }} {{ var1 }} xdp
