Subject: [xdp-hints] [PATCH bpf RFC 0/4] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash
Date: Tue, 28 Mar 2023 22:15:53 +0200	[thread overview]
Message-ID: <168003451121.3027256.13000250073816770554.stgit@firesoul> (raw)

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.
