+Subject: [PATCH] Revert "device: restart DHCP when the MAC changes"
+
+The commit causes problems with bridges. When a new port is attached
+the MAC of the bridge possibly changes and if we restart DHCP the
+bridge will get a different IP address.
+
+Revert the change until a better solution to the original problem is
+found.
+
+This reverts commit 905adabdba033bbfc33013d0ad203bd444131dc5.
