+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
