No description provided.

If you have 2 NICs with 4 queues and 1 socket with 8 cpus, you may be want
distribution like this:

eth0: [0, 1, 2, 3]
eth1: [4, 5, 6, 7]

so run:

```
rss-ladder-test eth0
rss-ladder-test --offset=4 eth1
```

If you have bugged NIC missing packets while RSS used on multiple CPUs
(it may be caused by DMA/RAM problems) you may use the following workaround:

bind all the NIC queues to **one** cpu, using:

```
rss-ladder --cpus 0 eth0
```

and distribute processing workload among other available CPUs using RPS.
