Message

Hi,

This is the v2 patch series for adding XDP support to stmmac driver.

Summary of the changes in v2:

1/6: Move IRQ affinity hint from dwmac-intel.c into stmmac_main.c inside
     stmmac_request_irq_multi_msi() and clear the IRQ affinity hint in
     stmmac_free_irq().
     Tested the patch with reloading the driver and confirmed that there
     is kernel warning during free_irq().

3/6: Fix build warning of unused variable found in
     https://patchwork.hopto.org/static/nipa/457321/12170149/build_32bit/stderr

4/6: Fix build warnig of unused variable found by lkp

There is no other patch changes in v2 for 2/6, 5/6 and 6/6 and the summary
for their changes are in v1 patch series:

 https://patchwork.kernel.org/project/netdevbpf/list/?series=457321

The v2 patch series are retested with the test steps listed in v1 and
the results looks good as per v1 patch series. The test are executed with
preempt-rt build and it also requires a fix that was sent to ML here:

 https://patchwork.kernel.org/project/netdevbpf/list/?series=457139

It will be great if community help test out these v2 patch series on your
platform and provide me feedback.

Thank you very much,
Boon Leong

Are there any (developer) boards available that can be bought online?
(that have HW for this Ethernet driver stmmac)

I'm interested in playing with the hardwares Split Header (SPH)
feature. As this was one of the use-cases for XDP multi-frame work.

At this point of time, I am not aware of any commercially available platform
yet as the EHL product is newly launched but we expect some of board
vendors will be start shipping them mid Q2-Q3 2021. I will surely provide
update if I come across something in future.
