Please be more exact and show the content of operstate, carrier files. Let's see what exactly goes wrong. If it's only docker0 and veth*, we may skip it like how we skip lo:
[ "${i#*/lo/}" != "$i" ] && continue
got it. Thanks, Yinsi
Thanks, Fengguang
one qemu may have serial net interfaces in /sys/class/net, just one is 'up' or '1' means network is ok, it will not sleep and directly run function export_ip_mac(), but actually eth0 not ready, it can't get mac and ip, so use ping can ensure save enough time for eth0.
