This seems to be related to commit 5ef44b3cb43b ("xsk: Bring back busy polling support") which relies on netif_queue_set_napi(). I see you implemented it for e1000, igc and so on. However, igb is missing. Do you have any plans to add the missing registration to igb? Just asking. Otherwise, I can send a patch for it.
