4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhang Shengju <zhangshengju@xxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 3f0ae05d6fea0ed5b19efdbc9c9f8e02685a3af3 ]
If the link is filtered out, loop index should also be updated. If not,
loop index will not be correct.
Fixes: dc599f76c22b0 ("net: Add support for filtering link dump by master device and kind")
