There are two separate things. 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.).
