Hopefully we can get some reviews now, but for inclusion in the tree you'll need to repost once net-next opens (should happen in the next few days): http://vger.kernel.org/~davem/net-next.html
[PATCH net-next v2 0/6] bcm63xx_enet: major makeover of driver
This patch series aim to improve the bcm63xx_enet driver by integrating the latest networking features, i.e. batched rx processing, BQL, build_skb, etc. The newer enetsw SoCs are found to be able to do unaligned rx DMA by adding NET_IP_ALIGN padding which, combined with these patches, improved packet processing performance by ~50% on BCM6328. Older non-enetsw SoCs still benefit mainly from rx batching. Performance improvement of ~30% is observed on BCM6333. The BCM63xx SoCs are designed for routers. As such, having BQL is beneficial as well as trivial to add. v2: * Add xmit_more support and rx loop improvisation patches. * Moved BQL netdev_reset_queue() to bcm_enet_stop()/bcm_enetsw_stop() functions as suggested by Florian Fainelli. * Improved commit messages.
