One is the "local-mac-address?" (note the '?' at the end), this a property of the /options node can bei set to either true or false. The second is the "local-mac-address" which can be a property of a NIC node and contains a MAC address. Currently FreeBSD doesn't pay attention to "local-mac-address?" and dc(4) always uses "local-mac-address" via OF_getetheraddr2() if it's there (onboard dc(4) on Netra X1, etc.).
