[TriLUG] questions regarding PPP and compression

[rpjday]

  i've just built kernel 2.4.18-pre1, then dumped CML2 and the
latest version of kbuild on top of that.  nothing like living
dangerously, i always say.

  anyway, got PPP running for that, but curious about a couple
of messages in /var/log/messages i remember from way back:

  modprobe: Can't locate module net-pf-4
  modprobe: Can't locate module net-pf-5

i vaguely recall that these had to do with PPP compression, no?
it's not serious since everything comes up fine and the next two
messages are that the PPP BSD and deflate compression modules are
registered.  but can someone refresh my memory what these messages
represented?

  also, there are two choices for PPP compression -- BSD and deflate --
with a note that deflate is the better choice.  does this actually
imply that i need only one of the two?  thanks.  most likely more
questions on the way as i hack around with kbuild and CML2.
