The VF-up script repeatedly deletes the first IPv4 address from hn until
ifconfig fails. Netlink-based ifconfig returns success when no address
remains, so the script can loop forever and block subsequent devd work.
Use ipv4_down() from the already-sourced network.subr to enumerate the
addresses and delete each explicitly. This also handles multiple
addresses without relying on the exit status of an empty deletion. The
behavior depends on ifconfig, not the VF hardware, so no device-specific
fallback is needed.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
For information on the CPU architectures and platforms supported by FreeBSD, see the FreeBSD website's Platforms page.
