| 4 | Subject: [PATCH] sdk_dpaa: set the skb queue mapping when looping |
| 5 | |
| 6 | Save the current CPU ID on ingress, when FSL_DPAA_DBG_LOOP is set. |
| 7 | Use the skb_set_queue_mapping() call instead of skb_record_rx_queue() |
| 8 | because the stack isn't involved and won't compensate for the additional |
| 9 | offset. |
