I noticed that the NHRP version number (ar$op.version) is the 17th
byte of the NHRP Fixed Header.  Asuming that future versions of NHRP
will be developed, it might be nice if the NHRP version number was
earlier in the packet, perhaps the first byte.  It would seem
that leaving the NHRP version number in the 17th packet would cause
future versions to work around this (hopefully fixed) location.

[For example, future protocol designers might determine that the
number of protocols will grow less rapidly than the number of IPv6
end nodes, and that a smaller protocol ID address space could
be used for NHRP...]

[[While I am whining, why don't we call the NHRP version field
something like nhr$version...]]
