DHCP reservations that depend on MAC addresses may fail if the server uses option 61 with UUID

DHCP issue has to do with the Intel NIC and what looks like the newest firmware changing how DHCP leases are requested. Basically, with the newest firmware (it appears) the Intel NIC is using UUID over option 61 to request a DHCP address. Unfortunately, our reservations have always been based on MAC address in the past. So, probably the easiest thing is to have HP investigate intel firmware for a version that uses MAC for Option 61 or request a change to the firmware to use MAC for option 61.
