[ovs-dev] eBPF and OVS

Hi all,

The recent DPDK 18.05 release provides BPF functionality for DPDK devices.

The BPF Library provides the ability to load and execute Enhanced Berkeley Packet Filters (eBPF) within user-space DPDK applications. It also introduces a basic framework to load/unload BPF-based filters on Eth devices (right now only via SW RX/TX callbacks). It also adds a dependency on libelf.

I'm just wondering if anyone is currently looking at BPF in OVS (either kernel or userspace). Specifically, if BPF will be supported in a future OVS release then is there a need to coordinate on the approach of how it is enabled?

Any thoughts/feedback welcome.

Thanks
Ian
