[bpf-next V2 PATCH 0/2] Implement sample code for XDP cpumap IP-pair load-balancing

2018-08-10 Thread Jesper Dangaard Brouer
Background: cpumap moves the SKB allocation out of the driver code, and instead allocate it on the remote CPU, and invokes the regular kernel network stack with the newly allocated SKB. The idea behind the XDP CPU redirect feature, is to use XDP as a load-balancer step in-front of regular kernel n
