It probably makes sense to add an ib_ptr (or rdma_ptr) to struct
net_device (along with all the other ones like ip_ptr, dn_ptr,
ax25_ptr, etc).
Is this ib_ptr or ipoib_ptr ? I would think iWARP devices would need
this.
I think that we can implement the CMA interface without adding this pointer by
using ARP and the private data in the CM REQ. Is it needed for any other purpose?
