netdevsim: add SR-IOV functionality

2017-12-02T23:27:58Z

dummy driver was extended with VF-related netdev APIs for testing SR-IOV-related software. netdevsim did not exist back then. Implement SR-IOV functionality in netdevsim. Notable difference is that since netdevsim has no module parameters, we will actually create a device with sriov_numvfs attribute for each netdev. The zero MAC address is accepted as some HW use it to mean any address is allowed. Link state is also now validated.

netdevsim: add bpf offload support

2017-12-02T23:27:57Z

Add support for loading programs for netdevsim devices and expose the related information via DebugFS. Both offload of XDP and cls_bpf programs is supported. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add software driver for testing offloads

2017-12-02T23:27:57Z

To be able to run selftests without any hardware required we need a software model. The model can also serve as an example implementation for those implementing actual HW offloads. The dummy driver have previously been extended to test SR-IOV, but the general consensus seems to be against adding further features to it. Add a new driver for purposes of software modelling only. eBPF and SR-IOV will be added here shortly, others are invited to further extend the driver with their offload models.
