eon(RFC 1070) is, basically, ISO CLNL encapsulated (with a small header for 
flags) inside IPv4 - indeed similar to gre, gif etc. In fact, gif has some
incomplete eon handling code.

So, logically, the ll addr is the (outer) IPv4 address. How *should*
it do this / what do the others do?

(And should it, maybe, be replaced by some glue in gif?)
