Subject: net/mlx5e: IPoIB, Add ethtool support to get child time stamping
 parameters
Patch-mainline: v4.16-rc1
Git-commit: 93b66472ce73920795f1477729620cce38fe34c0
References: bsc#1103990 FATE#326006

Add support to get time stamping capabilities using ethtool for
child interface.
Usage example:
	ethtool -T CHILD-DEVNAME

This change reuses the functionality of parent devices and does not
introduce any new logic.
