Originally arranged according to the PCI order, but this causes confusion if the NIC order is changed arbitrarily.
Root cause

1. Adjust the NIC layout to handle the load of dual parallel CPUs.

2. The original NIC mapping method cannot guarantee correct order if any changes occur under a CPU-balanced layout.

3. The number of NICs has reached the DPDK management limit.
Solution

1 & 2. Scan fixed PCI addresses based on the corresponding front-panel positions, and dynamically generate the port mapping results.

3. Modify the compilation parameters for DPDK.

Add new model(s).

- Array APV 7900 N → array_id=907902

- Array APV 9900 N → array_id=909902

- Array APV 11900 N → array_id=911902

Plug in the network cables in order, and compare with the results from the show interface command.
Use the N‑series license key instead of the original one.
