addrconf_notify() is printing that message, and I see it if you enable
IPv6 on an interface.  I don't think it is ixgbe specific.

it doesn't depend or preclude administrative UP, it is from the notify
handler getting a NETDEV_UP message, regardless of link state. 

you'll see some other message like:
ADDRCONF(NETDEV_CHANGE): eth6: link becomes ready

when you plug in the cable, all courtesy of Ipv6
