Subject: IB/core: Set speed string to SDR for invalid active rates
Patch-mainline: v4.17-rc1
Git-commit: 311d0da97480d19d4ecd57f3ee264e3c232d78e5
References: bsc#1103992 FATE#326009
Before commit f1b65df5a232 ("IB/mlx5: Add support for active_width and
active_speed in RoCE"), the mlx5_ib driver set default active_width and
active_speed to IB_WIDTH_4X and IB_SPEED_QDR.
Now, the active_width and active_speed are zeros if the RoCE port
is in DOWN state. The speed string should be set to " SDR" instead of
a blank string when active_speed is zero.
