====================
mlx5-updates-2017-06-20 (mlx5 IPoIB updates)

This series includes updates to mlx5 IPoIB netdevice driver (mlx5i),

1. We move ipoib files into separate directory, to allow it to grow
   separately in its own space
2. Remove HW update carrier logic from IPoIB and VF representors profiles.
3. Add basic ethtool support. (Rings options/statistics and driver info).
4. Change MTU support.
5. Xmit path statistics reporting.
6. add PTP support.

For the new ethtool ops, PTP (ioctl) and change_mtu ndos in IPoIB, we didn't add new
implementation or new logic, we only reused those callbacks from the already existing
mlx5e (ethernet netdevice profile) and exposed them in IPoIB netdevice/ethtool ops.
