Subject: [Intel-wired-lan] [Patch V3 5/9] i40e: Use numa_mem_id() to better support memoryless node
Function i40e_clean_rx_irq() tries to reuse memory pages allocated from the nearest node. To better support memoryless node, use
numa_mem_id() instead of numa_node_id() to get the nearest node with memory.
This change should only affect performance.
