[openib-general] [PATCH] netdevice.h: Add RDMA private pointer to the net_device structure

[Pradeep Satyanarayana]

Ok thanks for the explanation. So, I presume that means rdma_ptr will now
point to ib_device?

If so, one issue that strikes me as significant would be backward
compatability. My view is that one could continue to
use the IPoIB private data.
