[Patch V3 6/9] i40evf: 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. Signed-off-by: Jiang Liu --- drivers/net

[Patch v3 30/36] net/mlx4: Cache irq_desc->affinity instead of irq_desc

The field 'affinity' in irq_desc won't change once the irq_desc data structure is created. So cache irq_desc->affinity instead of irq_desc. This also helps to hide struct irq_desc from device drivers. Signed-off-by: Jiang Liu --- drivers/net/ethernet/mellanox/mlx
