CONFIG_IRNET
  Say Y here if you want to build support for the IrNET protocol.  If
  you want to compile it as a module (irnet.o), say M here and read
  <file:Documentation/modules.txt>.  IrNET is a PPP driver, so you
  will also need a working PPP subsystem (driver, daemon and
  config)...

  IrNET is an alternate way to tranfer TCP/IP traffic over IrDA.  It
  uses synchronous PPP over a set of point to point IrDA sockets.  You
  can use it between Linux machine or with W2k.
