Subject: net/mlx5e: IPoIB, Add PKEY child interface ethtool ops
Patch-mainline: v4.15-rc1
Git-commit: 6a910233c1eb19673dd0f37f1d72d7cdc419e176
References: bsc#1075020
Similar to VLAN interfaces child interfaces have limited ethtool
support. In current code the main limitation that does not
allow child interface ethtool configuration is due to shared
resources which are managed by the parent.
