cukinia_netif_is_up fails when it shouldn't

[ghost]

From the cukinia code:

_cukinia_netif_is_up() {
	local interface="$1"

	_cukinia_prepare "Checking if interface \"$interface\" is ${__not:+NOT }up"
	ip -o link show "$interface" up | grep -q "state UP" 2>&1
}

On my device, there is UP but no state UP:

root@my-yocto-beagleboneblack:~# ip -o link show eth0 up
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq qlen 1000\    link/ether 78:a5:04:c1:16:d0 brd ff:ff:ff:ff:ff:ff
