-Subject: [PATCH] bgmac: driver for GBit MAC core on BCMA bus
-MIME-Version: 1.0
-Content-Type: text/plain; charset=utf8
-Content-Transfer-Encoding: 8bit
-
-BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA
-based SoCs have gigabit ethernet provided by the GBit MAC core. This
-patch adds driver for such a cores registering itself as a netdev. It
-has been tested on a BCM4706 and BCM4718 chipsets.
-
-In the kernel tree there is already b44 driver which has some common
-things with bgmac, however there are many differences that has led to
-the decision or writing a new driver:
-1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44)
-2) There is 64bit DMA engine which differs from 32bit one
-3) There is no CAM (Content Addressable Memory) in GBit MAC
-4) We have 4 TX queues on GBit MAC devices (instead of 1)
-5) Many registers have different addresses/values
-6) RX header flags are also different
-
-The driver in it's state is functional how, however there is of course
-place for improvements:
-1) Supporting more net_device_ops
-2) SUpporting more ethtool_ops
-3) Unaligned addressing in DMA
-4) Writing separated PHY driver
