Re: [ovs-dev] [PATCHv4] userspace: Add GTP-U support.

Hi William, I think the question here is what is the main target functionality? 3-5/G VNF switching? Note that in many cases there is RSS issue here because GTP between two functions will have the exact same outer header, there is no port entropy. All the packets between two peers will get to

[ovs-dev] [PATCH v4] netdev-dpdk: add coverage counter to count vhost IRQs

When the dpdk vhost library executes an eventfd_write() call, i.e. waking up the guest, a new callback will be called. This patch adds the callback to count the number of interrupts sent to the VM to track the number of times interrupts where generated. This might be of interest to find out

[ovs-dev] [PATCHv5] userspace: Add GTP-U support.

GTP, GPRS Tunneling Protocol, is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS and LTE networks. GTP protocol has two parts: Signalling (GTP-Control, GTP-C) and User data (GTP-User, GTP-U). GTP-C is used for setting up GTP-U
