Hi all, I am new to PF_RING here, but Im very interested in it :). Recently I am working on a packet processing project which based on ovs (openvswitch), so I wonder if it is suitable to caputre/send on a virtual network interface, like veth, with PF_RING framework?
Before I post this issue, I have already tested the combination of veth and PF_RING, it seems work :), however, performance of sending packets is not so well, as I known, rx traffic is sent from kernel to userspace by mmap and ring buffer, but tx traffic is just sent by syscall "sendto". So my questions are: 1. If it suitable to receive/send packets on veth with PF_RING? 2. If question 1's answert is positive, then how can I promote the performance of packet sending? Thanks a lot.
