| Subject: [PATCH] sdk_dpaa: set the skb queue mapping when looping |
| |
| Save the current CPU ID on ingress, when FSL_DPAA_DBG_LOOP is set. |
| Use the skb_set_queue_mapping() call instead of skb_record_rx_queue() |
| because the stack isn't involved and won't compensate for the additional |
| offset. |
