Hi! This set contains a rough RFC implementation of a proposed [1] replacement for egdev cls_flower offloads. I did some last minute restructuring and removal of parts I felt were unnecessary, so if there are glaring bugs they are probably mine, not John's :) but hopefully this will give an idea of the general direction. We need to beef up the driver part to see how it fully comes together.
[1] http://vger.kernel.org/netconf2018_files/JakubKicinski_netconf2018.pdf slides 10-13 John's says: This patchset introduces as an alternative to egdev offload by allowing a driver to register for block updates when an external device (e.g. tunnel netdev) is bound to a TC block. Drivers can track new netdevs or register to existing ones to receive information on such events. Based on this, they may register for block offload rules using already existing functions. Included with this RFC is a patch to the NFP driver. This is only supposed to provide an example of how the remote block setup can be used.
