# Description: Get IPMI network information

our $VERSION = '1.3.0';

# IPMI network module for sysinfo client
# Author: R. W. Rodolico
# Date:   2016-09-17 

# 20171124 RWR
# Fixed where STDERR now goes to /dev/null
#
# 20191118 RWR v1.2.1
# in some cases, ipmitool is used only to access other devices over the network
# so it will not have information. Fixed so that if @temp is empty, will just exit
#
# 20230204 RWR v1.3.0
# look for specific IPMI files to determine if the driver is installed
# better than just checking @temp afterwards
#
# module to get network interface information for ipmi
# requires ipmitool (runs ipmitool lan print)
# NOTE: this takes the ipmitool output and parses it, so changes to 
#       this output invalidates this module
