Thanks for making the requested changes. There is a remaining issue with this patch, creating a flow in isolated mode causes a crash due to RX QPs not being allocated. You should temporarily make priv_flow_create_action_queue() call rxq_create_qp() when the target QP does not exist. Patch looks otherwise fine. -- Adrien Mazarguil 6WIND
