I am running a fully patched Fedora 21 system. We are trying to give it a long term lease in the DHCP server, but the MAC address sent changes on every boot. The MAC address seen at the DHCP server is not actually valid.

If you have a NIC that can't (or maybe does not) have a stable MAC address you can:

vi /etc/udev/rules.d/70-persistent-net.rules

# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="02:8b:02:81:f4:4a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

Or whatever you want for the MACaddr.
