v13: Rename the EAL get VF token function, and leave the freebsd type as empty.

v12: support to vfio devices with VF token and no token.

v11: Use the eal parameter to pass the VF token, then not every PCI
     device needs to be specified with this token. Also no ABI issue
     now.

v10: Use the __rte_internal to mark the internal API changing.

v9: Rewrite the document.

v8: Update the document.

v7: Add the Fixes tag in uuid, the release note and help
    document.

v6: Drop the Fixes tag in uuid, since the file has been
    moved to another place, not suitable to apply on stable.
    And this is not a bug, just some kind of enhancement.

v5: 1. Add the VF token parse error handling.
    2. Split into two patches for different logic module.
    3. Add more comments into the code for explaining the design.
    4. Drop the ABI change workaround, this patch set focuses on code review.

v4: 1. Ignore rte_vfio_setup_device ABI check since it is
       for Linux driver use.

v3: Fix the Travis build failed:
           (1). rte_uuid.h:97:55: error: unknown type name ‘size_t’
           (2). rte_uuid.h:58:2: error: implicit declaration of function ‘memcpy’

v2: Fix the FreeBSD build error.

v1: Update the commit message.

RFC v2:
         Based on Vamsi's RFC v1, and Alex's patch for Qemu
        [https://lore.kernel.org/lkml/20200204161737.34696b91@w520.home/]: 
       Use the devarg to pass-down the VF token.

RFC v1: https://patchwork.dpdk.org/patch/66281/ by Vamsi.

Haiyue Wang (2):
  eal: add uuid dependent header files explicitly
  eal: support for VFIO-PCI VF token
