See http://www.mavetju.org/weblog/html/cat_DHCP.html#00161 and
http://www.mavetju.org/weblog/html/cat_DHCP.html#00092 for examples
how I did it with APC Power Racks and Cisco phones.

I'm not sure what it expects with hexdata, you should give net/dhcpdump
a try to figure out what goes over the wire!
