====================
ftgmac100: Rework batch 5 - Features

This is the third spin of the fifth and last batch of
updates to the ftgmac100 driver.

This contains a few additional "features" such as:

 - Support for ethtool n-way reset
 - Multicast filtering & promisc support
 - Vlan offload
 - netpoll

And a couple of misc bits. This also adds the device-tree binding
documentation.

v2. - Addresses review comments and adds a new patch fixing a
      theorical ordering issue in my new NAPI poll implementation
    - Add a bug fix (Patch 8/9) for a potential ordering issue
      in the new NAPI poll code.

v3. - Rebase on net-next (fix conflict with an unrelated #include
      change series)
    - Update DT bindings better describing accepted phy-mode values
