      bgmac: driver for GBit MAC core on BCMA bus · dd4544f0
      Rafał Miłecki 提交于
      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

      drivers/net/ethernet/*: Enabled vendor Kconfig options · 88f07484
      Jeff Kirsher 提交于
      Based on finds for Stephen Rothwell, where current defconfig's
      enable a ethernet driver and it is not compiled due to the newly
      added NET_VENDOR_* component of Kconfig.
      
      This patch enables all the "new" Kconfig options so that current
      defconfig's will continue to compile the expected drivers.  In
      addition, by enabling all the new Kconfig options does not add
      any un-expected options.
