1. given a device, get its NUMA belongings
2. given a device, get its queues' irq numbers.
3. given a NUMA node, get its cpu id list.

This script simply does:
Detect $DEV's NUMA node belonging.
Bind each thread (processor of NUMA locality) with each $DEV queue's
irq affinity, 1:1 mapping.
How many '-t' threads input determines how many queues will be
utilized.
If '-f' designate

It's hard to benchmark 40G+ network bandwidth using ordinary
tools like iperf, netperf (see reference 1).
Pktgen, packet generator from Kernel sapce, shall be a candidate.
I derived this NUMA awared irq affinity sample script from
multi-queue sample02, successfully benchm
