  This patch series is intended to make a base for setting
  queue_index in the xdp_rxq_info struct in bpf/cpumap.c to
  the right index. Although that part I still didn't figure
  out yet,I m searching for my guidance to do that as well
  as for the correctness of the patches in this series.

What is the use case/movtivation behind this work?

The goal of the work is to have xdp programs have the correct packet RX 
queue index after being redirected through cpumap because currently the 
queue_index gets unset or more accurately set to 0 as a default in 
xdp_rxq_info. This is my current understanding.I still have to know how 
I can propogate that HW hint from the NICs to the function where I need it.
