It is not a macro but a Makefile variable.

Please provide the commit id where EAL was bumped.

typo: hierarchy

> +    ``rte_pci_driver``. These can now be used by any instantiated object of
> +    ``rte_driver``.
> +  * added ``rte_device`` class and all PCI and VDEV devices inherit from it
> +  * renamed devinit/devuninit handlers to probe/remove to make it more
> +    semantically correct with respect to device<=>driver relationship
> +  * moved hotplugging support to EAL. Hereafter, PCI and vdev can use the
