Hi,
This is the v4 patch series for adding XDP native support to stmmac.
Changes in v4:
5/6: Move TX clean timer setup to the end of NAPI RX process and
group it under stmmac_finalize_xdp_rx().
Also, fixed stmmac_xdp_xmit_back() returns STMMAC_XDP_CONSUMED
if XDP buffer conversion to XDP frame fails.
6/6: Move xdp_do_flush(0 into stmmac_finalize_xdp_rx() and combine
the XDP verdict of XDP TX and XDP REDIRECT together.
I retested the patch series on the 'xdp2' and 'xdp_redirect' related to
changes above and found the result to be satisfactory.
History of previous patch series:
v3: https://patchwork.kernel.org/project/netdevbpf/cover/20210331154135.8507-1-boon.leong.ong@xxxxxxxxx/
v2: https://patchwork.kernel.org/project/netdevbpf/list/?series=457757
v1: https://patchwork.kernel.org/project/netdevbpf/list/?series=457139
It will be great if community can help to test or review the v4 series
and provide me any input if any.
Thank you very much,
Boon Leong
