Messages in this thread | | | Subject | [PATCH bpf RFC-V2 0/5] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash | From | Jesper Dangaard Brouer <> | Date | Wed, 29 Mar 2023 18:28:58 +0200 |

Notice targeted 6.3-rc kernel via bpf git tree.
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 use the return value from bpf_xdp_metadata_rx_hash() to provide the RSS hash type.
Alternatively we disable bpf_xdp_metadata_rx_hash() in 6.3-rc, and have more time to nitpick the RSS hash-type bits.
