In general it is possible to use a tap interface to tunnel Ethernet packets. But this driver uses the EtherIP protocol defined in RFC 3378 which itself defines an own IP protocol for it (number 97). This protocol is also supported by different other operating systems (some of the major BSD versions). This driver makes Linux interoperable with these implementations. Regards, Joerg Roedel
