# NOTE 'ethtap' currently (200902) requires psim to
#      be patched -- also, it is only supported on
#      a linux host.
#      the 'ethtap' device transfers data from/to the
#      simulated network interface to/from a 'ethertap'
#      interface on the linux host (consult tun/tap
#      device documentation).
#      A very useful tool is 'tunctl' which allows for
#      configuring user-accessible, persistent 'tap'
#      devices so that psim may be executed w/o special
#      (root) privileges.
