This solves the problem of getting a list of all EtherIP devices. If
they use ARPHRD_ETHER and use an ioctl in the SIOCDEVPRIVATE space is
not a save way (not even if the ioctl uses ethip0, this device could be
owned by another driver if EtherIP is not present).
On the other hand, a new ARP type opens a lot of new problems. A lot of
userspace tools and libraries must be changed. So this solutions is not
perfect.

Cheers,
Joerg
