-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]
