[Pkg-ofed-devel] discovery of InfiniBand ports sometimes fails after firmware update

I would resend your question to linux-rdma at vger.kernel.org, it's much
more likely to be a driver issue than a packaging problem.

With that said, in the cases where ib1 doesn't come up, I would do:

    grep . /sys/class/infiniband/mlx4*/ports/*/link_layer

(I'm assuming you only have one ConnectX adapter in the system), and see
if the output looks like

    /sys/class/infiniband/mlx4_0/ports/1/link_layer:InfiniBand
    /sys/class/infiniband/mlx4_0/ports/2/link_layer:InfiniBand

I've seen cases where one port gets mis-negotiated as Ethernet.
