Currently net_iov stores a pointer to struct dmabuf_genpool_chunk_owner, which serves as a useful abstraction to share data and provide a context. However, it's too devmem specific, and we want to reuse it for other memory providers, and for that we need to decouple net_iov from devmem. Make net_iov to point to a new base structure called net_iov_area, which dmabuf_genpool_chunk_owner extends.

We've been there before. Instead of reinventing your own memory provider please enhance dmabufs for your use case. We don't really need to build memory buffer abstraction over memory buffer abstraction.
