bmips is using Broadcom B53 DSA driver which means the ethernet driver must compensate for 6 bytes tags from the internal switch. This means using NET_IP_ALIGN actually misaligns the skb, lowering performance significantly. Therefore napi_alloc_skb() which uses NET_IP_ALIGN is changed to netdev_alloc_skb(). Performance in iperf3 is increased from ~47Mbps to 52Mbps. Signed-off-by: Sieng Piaw Liew <liew.s.piaw@gmail.com> |
