Subject: [xdp-hints] [PATCH bpf RFC-V3 0/5] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash
Date: Thu, 30 Mar 2023 19:07:40 +0200	[thread overview]
Message-ID: <168019602958.3557870.9960387532660882277.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 change the function call signature via adding
a pointer value argument for 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.
