Hi,
I am running the DPDK version: 21.08.0 and Ubuntu 20.04.3 LTS.
I have an application that uses KNI to interface with the kernel.
I want to replace it with virtio_user ports as KNI will be deprecated in the future.
Most of the functionality I am able to replace but there is one thing I am struggling with.In KNI we can add functions that will be called in case the network stack makes a request. The following code shows this:
struct rte_kni *kni;
struct rte_kni_conf conf;
struct rte_kni_ops ops;
struct rte_eth_dev_info dev_info;
int ret;
/* Clear conf at first */
memset(&conf, 0, sizeof(conf));
conf.core_id = 0;
memset(&ops, 0, sizeof(ops));
ops.port_id = ppo->id;
ops.config_promiscusity = ippe_ppo_set_kni_promiscuous_mode;
ops.change_mtu = ippe_ppo_set_kni_mtu;
ops.config_network_if = ippe_ppo_set_kni_interface;
ops.config_mac_address = ippe_ppo_set_kni_mac_address;
kni = rte_kni_alloc(pktmbuf_pool[0], &conf, &ops);
And there is a handle_request function supplied by KNI that calls these functions when need be,
I haven't found any documentation on how to replace this functionality. I am no expert in how to set up and interact with the kernel stack, Some help on how to achieve this would be appreciated.
