[bpf,RFC,0/4] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash

Message

Jesper Dangaard Brouer March 28, 2023, 8:15 p.m. UTC

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.
