I will try to test with commit 8acacc40f733 ("net: ethernet: ti: am65-cpsw: Add minimal XDP support")
to see if it works there. If it does then I can do a bisect.
If you have better ideas please let me know. Thanks!

> Changes in v9:
> - In k3_cppi_desc_pool_destroy(), free memory allocated for pool.
> - In k3_cppi_desc_pool_create_name() function, remove unnecessary

> - In k3_cppi_desc_pool_create_name() function, move desc_infos alloc

> - For rx, do not build the skb upfront any more, Instead, give the page
