Subject: [PATCH] net/ethernet : set default assignment identifier to NET_NAME_ENUM

As noted in the original commit 685343fc3ba6 ("net: add
name_assign_type netdev attribute")

  ... when the kernel has given the interface a name using global
  device enumeration based on order of discovery (ethX, wlanY, etc)
  ... are labelled NET_NAME_ENUM.

That describes this case, so set the default for the devices here to
NET_NAME_ENUM to better help userspace tools to know if they might
like to rename them.
