Subject: [xdp-hints] [PATCH bpf V5 0/5] XDP-hints: API change for RX-hash kfunc bpf_xdp_metadata_rx_hash
Date: Fri, 31 Mar 2023 20:54:58 +0200 [thread overview]
Message-ID: <168028882260.4030852.1100965689789226162.stgit@firesoul> (raw)
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 providing the RSS hash type.
---
V5:
- Fixes for checkpatch.pl
- Change function signature for all xmo_rx_hash calls in patch1
Jesper Dangaard Brouer (5):
xdp: rss hash types representation
mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type
veth: bpf_xdp_metadata_rx_hash add xdp rss hash type
mlx4: bpf_xdp_metadata_rx_hash add xdp rss hash type
