I've completed a small temporary FDDI connection between DEC3000/300
and Personal DECstation, and they look like running fairly well so
far.  The Personal DECstation is running a fullscale kernel build over
NFS/TCP right now, and its load average is higher than 2 for last 30
minutes.  Both kernels are made from few days old -current source

The DEFTA reports it's a dual-attach device.  Similar trouble in

$ /sbin/ifconfig -m fta0
        media: FDDI Single-mode dual-attach
        status: inserted
        supported FDDI media:
                media Single-mode mediaopt dual-attach
        inet netmask 0xff000000 broadcast
