Subject: [PATCH net-next v2 0/6] stmmac: Add XDP support

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
