[Qemu-devel] [PATCH v2 3/6] e1000: wire new subsection to property


From: Dr. David Alan Gilbert (git)
Subject: [Qemu-devel] [PATCH v2 3/6] e1000: wire new subsection to property
Date: Wed, 28 Mar 2018 17:36:27 +0100

From: "Dr. David Alan Gilbert" <address@hidden>

Wire the new subsection from the previous commit to a property
so we can turn it off easily.
