Hi.

When the NetBSD mopd is started the first load attempt fails:
--- cut ---
[root@MissSophie ~]# /usr/sbin/mopd -d ex0   
mopd: not running as daemon, -d given.

And then the load hangs. The last line indicates some error in the
code, because the Ethernet address is wrong. The second load attempt is
successfull and the Ethernet address is showen correctly.

So I looked at the code and found the bug:

Ragge: Will you check in the fix or should I write a pr? 

The Linux-mopd is not affected by this bug.
