Thanks for your prompt response. The problem was seen on mlx4_en QDR.
When LRO enabled, for large packet than 1500 mtu, port1 can process this
packet, but port2 doesn't see this big packet at all from tcpdump trace.
I wonder whether there is any FW issue since I don't think the driver
handle two ports differently.
