pxeboot - Workaround BIOS breakage
* Some BIOSes (the one in my Gigabyte H97N-WIFI) continue to use the original
negotiated by the TFTP preloader even after we have negotiated a new IP
and used it in the udpopen. This will cause our dest_ip filter in
udpread() to implode. Detect and handle this case.
* Why does dhcpd hand out different IPs? I tracked one down to the PXE
BIOS sending a Client-ID option. However, our PXEBOOT DHCP and our
dhclient don't seem to send that option and also get different IPs.
* This won't fix post-boot breakage if dhclient rips the IP out from under
the NFS root mount in a pxebooted situation.
