[PATCH bpf V7 0/7] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Current API for bpf_xdp_metadata_rx_hash() returns the raw RSS hash value,
but doesn't provide information on the RSS hash type (part of 6.3-rc).

This patchset proposal is to change the function call signature via adding
a pointer value argument for providing the RSS hash type.

Patchset also disables all bpf_printk's from xdp_hw_metadata program
that we expect driver developers to use.

      selftests/bpf: xdp_hw_metadata default disable bpf_printk
      selftests/bpf: Add counters to xdp_hw_metadata
      xdp: rss hash types representation
      mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type
      veth: bpf_xdp_metadata_rx_hash add xdp rss hash type
      mlx4: bpf_xdp_metadata_rx_hash add xdp rss hash type
      selftests/bpf: Adjust bpf_xdp_metadata_rx_hash for new arg
