  • psim-top.in, psim-bottom: Added support for options -d (print device tree and exit), -h (usage info) and -n (enable NIC support).
  • psim-gdb-bottom: Added support for options -s (force sysv IPC), -h (usage info) and -n (enable NIC support). Allow user to override GDB variable from environment.
  • psim-shared: cat NIC properties into device file if the user had specified '-n'.
  • runtest-top.in: removed unsupported options -o, -d from usage info.
  • Property mode set to 100755

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