it isn't wrong, GHC EID is defined for 0-3 only so the first bit is
always zero. So 10110 E E N is right whereas:

1011000N -> Hop
1011001N -> Routing
1011010N -> Fragment
1011011N -> Destination

Seems like Mobility and IPv6 is not defined for GHC.

But I still don't know why iana put it for RFC6282 in a new entry on the
list for each EID and for GHC they did only one entry for the mask without
EID bits.
