+Subject: [PATCH] systemd: enable mac based names in NamePolicy
+
+The default NamePolicy for network interface names does not
+include names based on mac addresses.  Some BSPs, though, do
+not provide information to compute other names, so we enable
+mac names as a last resort.
+
+Upstream-Status: Inappropriate [enable feature]
