Hi,

> It is unclear where the interoperability problem comes in.

I'm sorry. A fix I submitted was a mistake.

 FreeBSD's current implementation expects 0x03, 0x00 as EtherIP header,
 but another implementation(UNIVERGE IX2015, products by NEC, Japan)
 transmits 0x30, 0x00. Then FreeBSD box discards EtherIP packets.

 I read RFC3378 and thought 0x30, 0x00 is correct.


The result of 'tcpdump -np -x proto etherip' at FreeBSD box is as
follows.

192.168.2.37: FreeBSD box
192.168.2.128: IX2015
MAC addresses were replaced with ****.
