I think better to try to avoid using 'rte_eth_devices' global variable as much
as possible, although it may not be possible always, but for this case it seems
it can be done.
Why not just pass "struct rte_eth_dev" as 'arg', instead of "struct ena_adapter"?

Similarly, instead of passing "struct ena_adapter" as "void *adapter_data", it
can be possible to pass "struct rte_eth_dev", as far as I can that chain has
more layers but still possible.
Meanhile, you can use "void *process_private;" field of "struct rte_eth_dev" to
keep process private eth_dev data, if you want.
