Some BSPs only provide information to construct a
predictable network interface named based on a mac
address, so we enable that NamePolicy option.

This policy has been adopted for sysvinit as of
commit 4a7b42fcf6981d3120c08091a7ed3d4d7bcd41f0.

+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]
