>Description:
changing status of port to OFF do not change status of igb device:
igb3: flags=8c02<BROADCAST,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=401bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,VLAN_HWTSO>
        ether a0:36:9f:00:66:a7
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
EXPECTED: 
 status: no carrier

only reboot helps.

On other hand. when port is OFF and it is turned on status is changed as expected from 'no carrier' to 'active. Turning off port on switch do not change status of link on igb. it stay to be 'active' despite on that port is OFF now
