Subject: [xdp-hints] [PATCH bpf-next V1 0/5] XDP-hints: XDP kfunc metadata for driver igc
List-Id: XDP hardware hints design discussion <xdp-hints.xdp-project.net>

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 timestamp
igc: add XDP hints kfuncs for RX hash
selftests/bpf: xdp_hw_metadata track more timestamps
