Subject: [xdp-hints] [PATCH bpf-next V2 0/5] XDP-hints: XDP kfunc metadata for driver igc
Date: Tue, 18 Apr 2023 15:30:37 +0200	[thread overview]
Message-ID: <168182460362.616355.14591423386485175723.stgit@firesoul> (raw)

Implement both RX hash and RX timestamp XDP hints kfunc metadata
for driver igc.

First patch fix RX hashing for igc in general.

Last patch change test program xdp_hw_metadata to track more
timestamps, which helps us correlate the hardware RX timestamp
with something.

---
To maintainers: I'm uncertain which git tree this should be sent
against. This is primary NIC driver code (net-next), but it's
BPF/XDP related (bpf-next) via xdp_metadata_ops.

Jesper Dangaard Brouer (5):
      igc: enable and fix RX hash usage by netstack
      igc: add igc_xdp_buff wrapper for xdp_buff in driver
      igc: add XDP hints kfuncs for RX hash
      igc: add XDP hints kfuncs for RX timestamp
      selftests/bpf: xdp_hw_metadata track more timestamps
