The problem is that {{ ansible_eth0.macaddress }} doesn't always report the
hardware macaddress.
I described this specific issue in my initial post.
For example, if eth0 is part of bond/link-aggregation-group, Ansible
returns the macaddress of the bond/LAG, NOT the macaddress of the eth0
interface itself.
Facter apparently obtains the macaddress another way, which in my
experience returns the actual macaddress, not the macaddress of the bond....
So that is my question.
How can I get Ansible itself to return the actual macaddress, or do I
always have to just use Facter?
