Log message:
implement support for MikroTik's Ethernet over IP protocol as eoip(4)
it is sort of like egre(4), but different enough to warrant separate
handling. more specifically, eoip sits under gre 1, not 0, and has
it's own protocol id (0x6400). the gre key field is mandantory (the
rest cannot be set) which is split into a 16 bit length field and
a 16 bit tunnel id. lastly, it has a keepalive mechanism where peers
send 0 length packets as hellos to each other periodically, which
has no equivalent in egre(4) and is different to the gre(4) keepalives.
