what's the point in specifying HWADDR anyway?

[JohnPreston]

How is it you get the HWADDR value to change ? That sounds odd, I never had that one before.
Though, the HWADDR is fairly important to keep track of in case something on the ARP is foobared and you cant find the original HWADDR again.

That is a discussable point.

The steps to reproduce are the same as for #1
every time I run ansible-playbook as specified there my ifcfg-files change.

[JohnPreston]

It truly doesn't change for me at all. I have added the option in my branch already to have the same kind of behaviours.
