Hello.
Is it possible to create a KNI interface at a bonding port?
My code that works perfectly fine with usual dpdk ports fails
when I try to use it with bonding ports.
rte_eth_dev_info_get(port_id, &dev_info);
conf.addr = dev_info.pci_dev->addr;
...
return rte_kni_alloc(pktmbuf_pool, &conf, &ops);
The code fails because pci_dev member of variable dev_info is NULL.
Is there any workarounds for this problem?
Thanks.

Hi Alex,
I previously ran into the same issue. I just used the PCI device
information from the primary slave of the bonded interface:

Hope that helps,
Cody

Hi, Cody. Thank you. It helped.
rte_eth_bond_primary_get() function is exactly what I needed.
