Hi,

Here is case, create vlan on eth5 say eth5.12, now pull out cable of
eth5 vlan interface link status is shown as down for both interfaces.
reboot machine and issue ifup eth5.12
after restart carrier status and ip link status is invalid,

Code:

cls:~ # cat /sys/class/net/eth5
eth5/ eth5.12/
cls:~ # cat /sys/class/net/eth5/carrier
0
cls:~ # cat /sys/class/net/eth5.12/carrier
1

7: eth5: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
link/ether 00:50:56:b0:00:15 brd ff:ff:ff:ff:ff:ff
8: pubeth1.4000@pubeth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 00:50:56:b0:05:c5 brd ff:ff:ff:ff:ff:ff
9: eth5.12@eth5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 00:50:56:b0:00:15 brd ff:ff:ff:ff:ff:ff

I am using sles 11 sp1
How to overcome this issue. This carrier should match with base device
carrier mii value for monitoring interface will be invalid because of
this.
