#    NAME
#      ifconfig.ksh - Network Interface Configuration
#
#    DESCRIPTION
#      Obtains network interface configuration information like flags, mtu,
#      inet and netmask per network interface.
#
#    NOTES
#      Currently this script is specific to Sun Solaris OS. For other OS,
#      the script may need to be modified.
