Subject: [PATCH net-next v2 0/6] bcm63xx_enet: major makeover of driver
Date:   Thu, 24 Dec 2020 22:24:15 +0800
Message-Id: <20201224142421.32350-1-liew.s.piaw@gmail.com>
Precedence: bulk

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.
