Subject: net/mlx5e: IPoIB, Add PTP ioctl support for child interface
Patch-mainline: v4.16-rc1
Git-commit: 08437c572c0873a696ceae92aff29f0ae334aeab
References: bsc#1103990 FATE#326006

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
