Hi Doug, Dave The following series adds support for managing SRIOV IB VFs in a standard way (rtnetlink, iproute2) through IPoIB ndo entries which translate to corresponding verbs calls. In IB networks, 64 bit GUIDs are used as the primary means of identification. To support that for VFs, we added a set_vf_guid ndo which is used to program the VF node and port GUID from the PF. Those verbs are implemented by the mlx5 driver along with some more changes needed in the driver, IPoIB and the IB core to support IB virtualization. We've copied netdev only on the 1st patch of the series, as the rest of it just uses the patch along with the existing ndos in IPoIB plus add things which are internal to the IB stack. The series is rebased against Doug's mlx5 branch and Leon's patch that extends the kernel ib device attr caps field to u64: https://patchwork.kernel.org/patch/8388931/ Eli Changes from V1: 1. Modify the patch handlign subnet prefix so it is implemented in the IB/core layer dropping the implementation in hardware driver layer.
