The V2 post LGTM re the points I was commenting on: the IB virt patch removed and the cover letter + change-log properly elaborate on how the feature is configured and what would be the resulted IB devices under the different variations, see one followup below: [..] > SR-IOV devices follow the same pattern as the physical ones.

Dan, so what happens w.r.t to the different combinations specified above, if on SRIOV setup where the admin enabled the feature, VFs land in VMs whose mlx5 driver doesn't have these changes? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
