Can you please move the block amaong the other ethdev drivers, as 
alphabetically sorted?

Is anything assinged to 'priv->dev_addr' to copy?
Also since there is a 'priv->dev_addr' field, why not use it directly, 
instead of allocating memory for 'eth_dev->data->mac_addrs'?
I mean why not "eth_dev->data->mac_addrs = &priv->dev_addr"?

These fields are not used in this patch, I guess some will be used in 
datapath patch.

Can you please only add fields that is used in the patch? This way it 
will be clear in which functionality that field is used and enable to 
detect not used fields.
We are accepting batch updates for base code, but this is dpdk related 
code, lets only add things that are used when they are used.
Same for all data structures.
