[ovs-dev] [PATCHv18] netdev-afxdp: add new netdev type for AF_XDP.

2019-07-18 Thread William Tu
The patch introduces experimental AF_XDP support for OVS netdev. AF_XDP, the Address Family of the eXpress Data Path, is a new Linux socket type built upon the eBPF and XDP technology. It is aims to have comparable performance to DPDK but cooperate better with existing kernel's networking stack.
