Hi Sebastian! We have a few of these: https://lore.kernel.org/all/0000000000008f77c2061c357383@google.com/ https://lore.kernel.org/all/00000000000079d168061c36ce83@google.com/ https://lore.kernel.org/all/000000000000357ea9061c384d6d@google.com/ tun's local XDP and XDP generic also need to be covered.
