  I don't think so.  I asked this about two weeks ago with no real
response other than that Jason Thorpe was working on the changes to do it
properly.  You can do it with simple pointer pushing since the header from
packet to packet is constant.

  Likewise.  I'd love to use my IPX as my DSL gateway.  I worked on an IRIX
implementation of PPPoE on the weekend.  Got a cheesy PTY-based solution
basically done except that IRIX PPP doesn't like the other end using an MTU
less than 1500 (sigh).  I've put off learning STREAMS and DLPI until I
solve this since sticking my code in the kernel will just make it not work
faster.

  RFC2516 is *very* Ethernet-centric, so there's no point in worrying about
supporting other things.  But it would be good to have a polite complaint if
one tried to run it over something else, yes.
