ether_ifattach() is called, and ether_ifattach() calls if_attach().
if_attachdomain1() is called from if_attach().  So,
ifp->if_afdata[AF_INET6] should be initialized.
However, domain_init_status was introduced, and it may prevent
if_attachdomain1() from initializing ifp->if_afdata.  So, I suspect
the state of domain_init_status.

Sincerely,
