Subject: [xdp-hints] [PATCH bpf RFC-V2 0/5] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash
Date: Wed, 29 Mar 2023 18:28:58 +0200 [thread overview]
Message-ID: <168010726310.3039990.2753040700813178259.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.
Alternatively we disable bpf_xdp_metadata_rx_hash() in 6.3-rc, and have
more time to nitpick the RSS hash-type bits.
