Then, at flush time (napi_complete_done(), napi_poll(), or napi_busy_loop()), call netif_receive_skb_list_internal() on the list. We'd like to do that in napi_gro_flush(), but it's not called if !napi->gro_bitmask, so we have to do it in the callers instead. (There are a handful of drivers that call napi_gro_flush() themselves, but it's not clear why, or whether this will affect them.) Because a full 64 packets is an inefficiently large batch, also consume the list whenever it exceeds gro_normal_batch, a new net/core sysctl that defaults to 8.
