description:
For netboot via DHCP, "next-server" in dhcpd.conf(5) is mandatory.

Pointed out by Anders Gustafsson on port-hp300@.
 https://mail-index.netbsd.org/port-hp300/2021/04/21/msg000201.html

Should be pulled up to netbsd-8 and netbsd-9.

XXX: kernel should use the dhcpd/bootp server address for nfsroot
     if the specified next-server (siaddr) is 0.0.0.0?
