If undionly.kpxe fails to communicate, but ipxe.usb/iso/lkrn works, it
would be useful to see a packet capture from the perspective of the DHCP
server when booting each of these two drivers on the same hardware. It
would be most useful if you only include packets that either have the
troublesome machines MAC address set as source or destination (and any
broadcast packets).

With this the developers should be able to pinpoint the difference.
Remember to capture full packets (-s 0 if using tcpdump). Anything else
has limited usefulness for debugging.

Also mention which version you were using and if you had any
non-standard configuration options set in src/config/*.h or on the make
command line.
