net/mlx5e: IPoIB, Show unknown speed instead of error
ethtool is returning an error for unknown speeds for the IPoIB interface: $ ethtool ib0 netlink error: failed to retrieve link settings netlink error: Invalid argument netlink error: failed to retrieve link settings netlink error: Invalid argument Settings for ib0: Link detected: no After this change, ethtool will return success and show "unknown speed": $ ethtool ib0 Settings for ib0: Supported ports: [ ] Supported link modes: Not reported Supported pause frame use: No Supports auto-negotiation: No Supported FEC modes: Not reported Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: Unknown! Duplex: Full Auto-negotiation: off Port: Other PHYAD: 0 Transceiver: internal Link detected: no Fixes: eb234ee9d541 ("net/mlx5e: IPoIB, Add support for get_link_ksettings in ethtool") Signed-off-by: Dragos Tatulea <dtatulea@nvidia.com> Reviewed-by: Gal Pressman <gal@nvidia.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
