# for the specific node i.e.:
# NICNODE - the node name
# NICIPS - comma separated list of ips per NIC
# NICHOSTNAMESUFFIXES - comma spearated list of hostname suffixes per NIC
# NICTYPES - ethernet or infiniband
# NICCUSTOMSCRIPTS - script to configure nic, i.e. configeth or configib
# NICNETWORKS - network and subnetmask for the adapter.
