Due to the scarce information in the internet for how to setup ISC DHCP6
configs to manage UEFI pxe/http boot from various client, here is an example
config to accomplish that by means of the vendor class id. The config is also
used to identify and verify the fix in the patch.
Hopefully it helps other people scratching his head trying to figure out the
config (like me) to manage various NBP clients in DHCP server.
Thanks. :)
