 base-commit: 07e27ad16399afcd693be20211b0dfae63e0615f
 this is the commit of tag: v6.17-rc7 on the mainline.
 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.

But why do you need a kfunc getter? You can already get rxq index
via xdp_md rx_queue_index.
