[Bug 278043] Diskless nfs root BOOTP/DHCP Broken

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278043

--- Comment #6 from Mark Johnston <markj@FreeBSD.org> ---
The basic reason is that we cannot easily use raw sockets to receive UDP
packets - they belong to udp_input().  dhclient actually uses the BPF interface
to send/recv UDP packets for DHCP, but I think that's a bit too inconvenient in
the kernel.  We can perhaps use a separate UDP socket for receiving packets,
but that's a bit inconvenient.  Or, we can perhaps temporarily override the
ipproto registration when bootp is running.

(In reply to Richard Wai from comment #3)
We could do that, but I'd prefer not to if there's some other option.  We use
INADDR_ANY as a sentinel value in various places in the pcb layer, so life is
better if we can always say that it's an invalid value.
