for me, the most important thing at the moment, is to run our system on xen guest (aka DomU), with the full functions. the performance could be a secondary consideration. most of time, for our guests, full functions, with the acceptable performance, is fine.do we have plan to support xen netfront pmd in dpdk ? in my humble opinion, limited performance is better than "not work" .
If you only care about the functionality, you can try AF_PACKET or pcap PMD. Thanks, Jianfeng
