> If CONFIG_IRDMA isn't enabled but there are ice NICs in the system,
> the driver will prevent full devlink dev param show dump because its
> rdma get callbacks return ENODEV and stop the dump. For example:
>  $ devlink dev param show
>  pci/0000:82:00.0:
>    name msix_vec_per_pf_max type generic
>      values:
>        cmode driverinit value 2
>    name msix_vec_per_pf_min type generic
>      values:
>        cmode driverinit value 2
>  kernel answers: No such device
> 
> Returning EOPNOTSUPP allows the dump to continue so we can see all
> devices'
> devlink parameters.
