Hi, I noticed that, other than most networking drivers, the `tun` driver has no support for the XDP metadata area yet. (xdp->data_meta == xdp->data + 1) Is there a specific reason, why it cannot not be implemented for the tun driver, or is this just because nobody came around to implement it yet? The headroom reserved in the tun driver seems high enough (TUN_RX_PAD + XDP_PACKET_HEADROOM), so I would think that it should fit..? Thanks! Marcus Wichelmann Hetzner Cloud GmbH
