"""
NM may use ifcfg files as its storage format for connections via the
ifcfg-rh settings plugin.
This is the default option under RHEL/Centos/Fedora.
When a connection is defined, it is saved in an ifcfg file, however,
the filename is not recorded in NM records.
In some scenarios, it is useful look for the ifcfg filename based on
a given connection or the other way around, looking for the connection
given the filename.
