>
> Loading ecore clients (PMD or linux kernel driver) having different ecore
> versions concurrently, is problematic from device's init/config perspective.
> This
> fix changes driver's default load parameter to have ecore version validated by
> MFW. All ecore clients having matching ecore version should be allowed to
> load, otherwise MFW should fail the load request.

Dropping this patch for now, please ignore this.
Internal discussions are going on regarding this patch. I will send a new
patch after the discussions.
Thanks,
Devendra
