I hate to pick nits but there is already a bool usage in internal
function (static) in ethdev.


static bool
is_allocated(const struct rte_eth_dev *ethdev)
{
	return ethdev->data->name[0] != '\0';
}

Using bool functions doesn't really generate different code. It is is more
about using modern C conventions.
