[RFC PATCH 0/6] eBPF RSS support for virtio-net

Basic idea is to use eBPF to calculate and steer packets in TAP. RSS(Receive Side Scaling) is used to distribute network packets to guest virtqueues by calculating packet hash. eBPF RSS allows us to use RSS with vhost TAP. This set of patches introduces the usage of eBPF for packet steering and
