The EtherIP implementation found on FreeBSD 6.1, 6.2, 6.3, 7.0, 7.1, and 7.2 had an interoperability issue because it sent the incorrect EtherIP packets and discarded the correct ones. This change introduces the following two flags to gif(4): accept_rev_ethip_ver: accepts both correct EtherIP packets and ones with reversed version field, if enabled. If disabled, the gif accepts the correct packets only. This flag is enabled by default. send_rev_ethip_ver: sends EtherIP packets with reversed version field intentionally, if enabled. If disabled, the gif sends the correct packets only. This flag is disabled by default. These flags are stored in struct gif_softc and can be set by ifconfig(8) on per-interface basis. Note that this is an incompatible change of EtherIP with the older FreeBSD releases. If you need to interoperate older FreeBSD boxes and new versions after this commit, setting "send_rev_ethip_ver" is needed.
