ip tuntap enumerates devices using /sys/class/net which is unusual.
Should we replace this enumeration using /proc/net/dev like "ip tunnel" ?
After "unshare -n" maybe mounting /sys should not be required for
proper iproute2 behavior.
At least ip command should adopt a common enumeration method.
What do you think ?
Thanks.
