Yes, it is an error from this commit:
	http://dpdk.org/browse/dpdk/commit/?id=88701645c98c9c88
These definitions were moved from a GPL file so they should keep the GPL header.
Then it is used in EAL:
	http://dpdk.org/browse/dpdk/commit/?id=ff0b67d1c868c19
So it must be dual licensed, like for rte_pci_dev_ids.h:
	http://dpdk.org/browse/dpdk/tree/lib/librte_eal/common/include/rte_pci_dev_ids.h
