Best way to convert RHEL 7.4 ifconfig -a dump to RHEL 6.3


Hi,

we have a script which uses ifconfig -a dump, parses it & gets required data. Now in RHEL 7.4 the ifconfig -a dump is changed as compared to RHEL 6.3 .

Now i need way to convert this dump back to the way it looks in RHEL 6.4 . So what is the best way to do it?

sample dump :
In RHEL 6

You are the only person that knows what data you are interested in.
Adapt the script to handle either as input.
