Yes would be nice to remove the name from rte_eth_dev_data.

Yes it is in rte_eth_dev_attach_secondary().
This secondary process forces us to write ugly data structures.

Yes I agree.
There are probably other places where we can avoid using this field.
I see rte_eth_dev_get_name_by_port() and rte_eth_dev_get_port_by_name()
using rte_eth_dev_data[port].name.
