commit cf1a3b35382c10ce315c32bd2b3d7789897fbe13 upstream.

As preparation for the next patches, we store the MAC address,
parsed during the vdpasim_create(), in a buffer that will be used
to fill 'config' together with other configurations.

I'm not sure why this series is in stable. It is not documented to fix
anything bad.

Should this be static?

Yes, there is already a patch [1] queued by Michael but not yet upstream. When it will be merged upstream I will make sure it will be backported.

Thanks,
Stefano
