You are right. And, the patches are not submitted by me.
As far as I know, our customers don't care the situation.
They would provide the guide to describe it. Besides, the
feature could be disabled through BIOS.
In addition, the Dell limits the specific devices to
use the feature of MAC passthrough. It could reduce such
situation.
