[DHCP Relay agent] send packets to different dhcp servers based on client options

[Alex Burger]

Hi Stephan.

I wrote a patch for the DHCP Relay server back in 2008 that will send DHCP
requests to different servers based on the client MAC address.  I used it
to implement a 'Master PXE server' to direct different types of clients to
different PXE servers.  It may work for what you are trying to do, but it's
limited to a file containing MAC address to DHCP server mappings.

I haven't tried applying the patch to the latest release of ISC DHCP, but I
can try it later if you are interested.
