Thanks Robin! Looks like that commit went into Kernel version 6.1, but I see the behaviour change in 5.15 itself. And the 5.15 code includes two sets of receive groups - https://elixir.bootlin.com/linux/v5.15/source/drivers/net/ethernet/mellanox/mlx5/core/en.h#L167 My app uses AF_XDP for TX only and I'm wondering if there's a different commit for the TX queues in mlx5?
