A little investigation shows that the IPv6 addrconf module is assuming
"link up" at initialization and is running DAD and RS while the cable is
still disconnected.  When I connect the cable, the PHY and the gianfar
driver detect "link up" but the addrconf module doesn't see the
transition.

Probably fixed by this patch last week:
