[dpdk-dev] [PATCH v4 19/70] net/enic: use contiguous allocation for DMA memory

[Anatoly Burakov]

All hardware drivers should allocate IOVA-contiguous
memzones for their hardware resources.

Notes:
    v4:
    - Use new memzone flag instead of new API
    - Remove experimental API from build files
    
    v3:
    - Add experimental API to build files
    
    v3:
    - Moved patch earlier in the patchset
    - Allowed experimental API in Makefile
    
    v3:
    - Moved patch earlier in the patchset
    - Allowed experimental API in the build system
