--- Comment #25 from mike@sentex.net ---
I have confirmed this behaviour on RELENG_12 (r367411)

e.g
ifconfig vlan6 create 10.6.6.6/28 vlandev igb1 vlan 6
ifconfig vlan7 create 10.7.7.7/28 vlandev igb1 vlan 7

# dmesg | tail -19
vlan5: promiscuous mode enabled
igb1: promiscuous mode disabled
vlan5: promiscuous mode disabled
igb1: promiscuous mode enabled
igb1: promiscuous mode disabled
igb1: link state changed to DOWN
vlan5: link state changed to DOWN
vlan6: link state changed to DOWN
igb1: link state changed to UP
vlan5: link state changed to UP
vlan6: link state changed to UP
igb1: link state changed to DOWN
vlan5: link state changed to DOWN
vlan6: link state changed to DOWN
vlan7: link state changed to DOWN
igb1: link state changed to UP
vlan5: link state changed to UP
vlan6: link state changed to UP
vlan7: link state changed to UP

ie. with each vlan created, igb1 and all the VLANS transition with a full
carrier down/up (confirmed from the switch they are connected to)
