The outputs of various commands you suggested are as below:

# demesg -n 7
# ip link set eth0 up
# no such device
# echo $?
# 255
# ip addr show
1. Intel: <BPOADCST, MULTICAST> mtu 1500 qdisc noop qlen 1000
   link/ether 00:02:a5:a4:3f:bf brd ff:ff:ff:ff:ff:ff
2. lo <LOOPBACK,UP> mtu 16436 qdisc noqueue
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
3. dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop
   link/ether 02:78:ca:b5:ab:f1 brd ff:ff:ff:ff:ff:ff
4. gre0: <NOARP> mtu 1476 qdisc noop
   link/gre 00:00:00:00 brd 00:00:00:00

Does this indicate something to you?

Thanks and Regards
