pass-through
The patch increases libnl sock receive buffer size to 1M, and nl_recv() doesn't return error when destroying domain with 512 network interfaces.

This feels like something that perhaps should be configurable - that is some /etc/libvirt/libvirtd.conf variable; otherwise, we'll keep hitting some conflated maximum based on the size of something.
1 MB matches what systemed/udevd uses, so if we hit that limit, then the system as a whole is going to struggle already. So I don't think we need make it configurable.
