Hi all,
I have question regarding function netdev_open and dpdk.
I’m trying to get stats from dpdk interface by:
My example code:
struct netdev_stats stats;
const char *mtype = "dpdk";
struct netdev *dev = 0;
if(0 != netdev_open("dpdk0", mtype, &dev)) {
printf("****port open failed\n");
} else {
int ret = netdev_get_stats(dev, &stats);
if(0 != ret) {
printf("Failed to get stats from device\n");
} else {
printf("Get stats success!");
}
netdev_close(dev);
which lead to error:
2016-01-11T13:43:39Z|00001|netdev|WARN|could not create netdev dpdk0 of unknown type dpdk
****port open failed
Also when I enum the types by:
struct sset types;
const char *type;
sset_init(&types);
netdev_enumerate_types(&types);
SSET_FOR_EACH (type, &types) {
printf("Enumerated type: %s\n", type);
}
sset_destroy(&types);
Then there is no “dpdk” type.
** BUT **
When I run command
---
utilities]# ./ovs-vsctl show
Bridge "br-enp9s0f0"
Port "phy-br-enp9s0f0"
Interface "phy-br-enp9s0f0"
type: patch
options: {peer="int-br-enp9s0f0"}
Port "br-enp9s0f0"
Interface "br-enp9s0f0"
type: internal
Port "dpdk0"
Interface "dpdk0"
type: dpdk
---
I tried to put my code directly into ovs-vsctl, but with the same error result.
I’m quite lost what I’m doing wrong.
Can somebody please point me what I’m doing wrong? Or how I can get stats from OVS using dpdk?
(I only found API directly in DPDK, but this is not preferred way)
Thanks for any help
And have a nice day ☺
Jarek
