This is the same as IPIP, but then to encapsulate Ethernet frames in IP
packets. Why they wrote an RFC for this while there already is GRE is
beyond me. Anyway, this protocol isn't really suited for VPNs:

- it doesn't support encryption (you either have to use IPsec to encrypt
  the outer IP frame or encrypt the traffic beforehand).

- it doesn't work through NATs

- you cannot run more than one "EtherIP tunnel" between two hosts at the
  same time
