Yes, the first.  And none of this will work if the 2nd...nth interfaces
have any network-layer addresses assigned, which means before joining
them to the agr you'll need to remove the automatically assigned IPv6
link-local address.

Are you really using NetBSD 1.6.3, as you say above, or is it a typo
for 6.1.3?  In NetBSD 6 the infrastructure for resetting the interface
MAC addresses is already there and you can just look at a driver like
'wm' to see how it works.  In NetBSD 1.6, though...
