Re: [PATCH net-next v2 0/4] bnxt_en: add XDP RSS hash metadata support

This series adds XDP RSS hash metadata extraction support for the bnxt_en
driver and includes selftests to validate the functionality. I was able
to test this on a BCM57414 NIC.

The driver changes introduce a bnxt_xdp_buff wrapper that carries
hardware RX completion descriptors alongside the xdp_buff, then use it
to implement bpf_xdp_metadata_rx_hash().

The selftest changes refactor common XDP/BPF helpers into a shared
library and add a new xdp_metadata test that verifies RSS hash
extraction for TCP and UDP traffic via device-bound XDP programs.

Changes from v1:
- selftests: moved tests into net/hw
- selftests: fix pylinter errors
- selftests: add check for no error count
- bnxt_xdp: followed RCT for variable declaration
- rebased on net-next 

Thanks for putting the summary in the cover letter.

In the future, you might consider including a summary in the patches
themselves to make it more clear what changed in each patch.

As an example of how you might do it in the future, check out this recent
patch [1].
