From 83c9e13aa39aed5cf9a2f8dd69770b7c35ba1281 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 1 Dec 2017 15:08:58 -0800 Subject: netdevsim: add software driver for testing offloads 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.
