Hi,

I'm using DPDK 17.11.5 to bond two interfaces via the vdev syntax, however the two interfaces are on the same NIC and share the same PCI address.

Is there a way to reference them using the devargs syntax by MAC address? It is discussed here https://patches.dpdk.org/patch/33808/

E.g.
class=eth,mac=00:11:22:33:44:55

I don't see this as an option in the bond PMD for slave interfaces even in the latest 19.05 release.

I'm trying to set this using VPP e.g. normally:
vdev eth_bond0,mode=1,slave=PCI1,slave=PCI2

Thanks
Greg

It is implemented at ethdev level as a port iterator:

In order to use this syntax with bonding slaves,
I think a patch is required.

Probably yes.
You can try to do it, and work with Chas for help.
