From: Honggang Li <ho...@redhat.com> Before the mlx5 RoCE port negotiate the active rate and width with remote side, the mlx5_ib driver set them to zero.
The tool 'ibstat' of 'infiniband-diags' package will panic as it read invalid width from the sys file. Set the active widths to lowest valid vaule as what ib_core module did for invalid rates.
