It would make more sense to store the struct ib_device pointer in the
struct rdma_netdev.

Agree that it shouldn't be a function parameters.
For opa_vnic, I found it convenient to store ib_device pointer in client and
device private structures as those will be available in most places anyhow.

If vnic uses it too, then lets add the ib_device and port num to
rdma_netdev itself?

Agree, at the end this rdma_netdev is intended for the drivers/infiniband
and it is better to have this binding (rdma_netdev and ib_device) as early as possible.

Thanks
