4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Balakrishnan Raman <ramanb@cumulusnetworks.com>


[ Upstream commit efb5f68f32995c146944a9d4257c3cf8eae2c4a1 ]

Mac aging is applicable only for dynamically learnt remote mac
entries. Check for user configured static remote mac entries
and skip aging.
