    Tried your series with SPDK (w/o and w/ enable_driver_sdk).
    I think the same, and the error is likely due to the file rename.

    $ make
      CC lib/env_dpdk/env.o
    In file included from env.c:39:0:
    env_internal.h:64:25: error: field ‘driver’ has incomplete type
      struct rte_pci_driver  driver;
    env_internal.h:75:59: warning: ‘struct rte_pci_device’ declared inside
    parameter list [enabled by default]
     int pci_device_init(struct rte_pci_driver *driver, struct
    rte_pci_device *device);

     int pci_device_fini(struct rte_pci_device *device);

    make[2]: *** [env.o] Error 1
    make[1]: *** [env_dpdk] Error 2
    make: *** [lib] Error 2

    So basically, SPDK needs some updates since it has its own pci drivers.
    I copied some SPDK folks for info.

    *Disclaimer* I only checked it links fine against my 21.11 dpdk env,
    and did not test the other cases:
