  The "local <IP>" part comes directly from HE instructionpage.  And it works,
which is not the case for "local dev eth0" version:

$ ip tunnel add he-ipv6 mode sit remote 216.66.80.162 local dev eth0
Error: an IP address is expected rather than "dev"

$ rpm -qf /usr/sbin/ip
iproute-3.15.0-1.fc21.x86_64

  (adding "dev" works if I ALSO provide "local ip" part:
ip tunnel add he-ipv6 mode sit remote 216.66.80.162 local 109.107.25.67 ttl 255 dev eth0 )

  After putting in interface name tunnel is still not created:

# SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd
timestamp of '/etc/systemd/network' changed
              he: loaded sit
sd-rtnl: discarding 20 bytes of incoming message
could not add new link

And no more lines mentioning neither "tunnel" nor "he".
