>
> The second patch adds the sample tc action, which uses psample to randomly
> sample packets that match a classifier. The user can configure the psample
> group number, the sampling rate and the packet's truncation (to save
> kernel-user traffic).
>
> The last two patches add the support for offloading the matchall-sample
> tc command in the mlxsw driver, for ingress qdiscs.

> An example for psample usage can be found in the libpsample project at:

Series applied, thank you.
