Dave could you include this in next update to 4.1 stable update?

Subject: [PATCH] Revert "dev: set iflink to 0 for virtual interfaces"

commit 95ec655bc465ccb2a3329d4aff9a45e3c8188db5 upstream.
It should be applied to 4.1.y stable tree.

This reverts commit e1622baf54df8cc958bf29d71de5ad545ea7d93c.

The side effect of this commit is to add a '@...E' after each virtual
interface name with a 'ip link'. It may break existing scripts.
