Is there a way to control what ethernet port gets mapped to each port_id in DPDK?
>From what I've seen, it looks like the port_id values just get assigned based on the order they come back in the PCI probe/scan. Ideally, I'd like to have the port_id values map reasonably directly to the customer-facing labels on my appliance. Label : port_id ------ ------- Port 1 : 0 Port 2 : 1 Port 3 : 2 etc. The PCI bus:slot.function values of the ethernet ports doesn't just sort cleanly (no surprise). I can work around it at higher levels, but it is a lot easier for debugging and stats if there is a way to control how DPDK maps physical ports to port_id values. I didn't see anything in the docs or example apps so presumably the answer is no, but thought I'd ask just in case. Is that something other folks would find useful? Thanks, Jay
