[vpp-dev] vpp io threads
Hi Team, I am trying to see how to distribute traffic between multiple worker threads in the absence of RSS. I believe there are I/O threads for handling input and and dispatching to worker threads. src/vlib/threads.c: " /* Initial barrier sync, for both worker and i/o threads */ Is there any documentation for I/O threads and binding them to interfaces ? Regards, Shiv ___ vpp-dev mailing list vpp-dev@lists.fd.io https://lists.fd.io/mailman/listinfo/vpp-dev

[vpp-dev] Docker containers
Hi VPP Team, I am trying to interface docker containers to VPP through an vhost-user device. The page here ( https://wiki.fd.io/view/VPP/Use_VPP_to_connect_VMs_Using_Vhost-User_Interface) explains how to do it for VMs. Is there any page that explains it for docker containers ?
