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.
