> Subject: [PATCH net] drivers: net: ice: fix devlink parameters get
> without irdma
>
> 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.
