Appreciate your insights on: (1) Do you have plan to enable it in DPDK vhost user? (2) How about another similar feature, promisc mode enable/disable?

Yes, I plan to propose this for v17.05 release. For vhost-user backend, the op is to notify the backend with the MTU value set in QEMU, so that it can ensure packets sent won't be bigger. > > (2) How about another similar feature, promisc mode enable/disable? This is ont something we have considered yet. Are you willing to work on it? Thanks, Maxime > > > Thanks, > > Jianfeng > ^ permalink raw reply [flat|nested] 5+ messages in thread
