--- Comment #7 from Miguel Pérez Regueiro <miguelpr4242@gmail.com> ---
I also hit this on 15.1-RELEASE with Firefox's HTTP/3 stack (Neqo) under
Linuxulator. Neqo enables IP_PKTINFO on its UDP sockets and gets ENOPROTOOPT.

Would the preferred direction still be to implement IPv4 packet-info support in
the FreeBSD network stack and then add IP_PKTINFO support to Linuxulator?
