Subject: [net-next 06/10] net/mlx5e: IPoIB, Add PTP ioctl support for child interface

From: Feras Daoud <ferasda@...lanox.com>

Add support to control precision time protocol on child interfaces
using ioctl.

This commit changes the following:
- Change parent ioctl function to be non static
- Reuse the parent ioctl function in child devices
