This is only used in the ESX driver where, when set to "no", it will

the ESX server telling it not to check it either.
This allows keeping a deterministic MAC address which can be useful for
licensed software which might dislike changes.

* **Improvements**
While you get bonus points for remembering to document this change, it
should go into a separate patch, because keeping it in a single one
usually leads to conflicts on backports.
But anyway, looking at virVMXFormatEthernet() - why don't we set all
MACs 'static'? Alternatively, we can use @mac_generated member to
determine whether the MAC address was provided by user or automagically
generated (and use static/generated addressType accrodingly)?
I mean, this attribute you are adding (the code is correct though)
should be last resort. Can you please elaborate more?
