A similar field has been added recently:

	http://dpdk.org/browse/next/dpdk-next-net/tree/lib/librte_ether/rte_ethdev.h#n1074

	/** Generic device capabilities */
	uint64_t dev_capa;

It is for flags DEV_CAPA_*
Note that the prefix should be fixed to RTE_ETH_DEV,
and the doxygen comment should mention the flags prefix.
Qi, please fix.

I think dev_capa and dev_flags are the same thing.
They could be merged.

It seems you tried to re-align but it fails.
Better to use spaces for alignment.
