3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Devesh Sharma <[email protected]> commit 8b0f93d9490653a7b9fc91f3570089132faed1c0 upstream. During create-ah from userspace, uverbs is sending garbage data in attr.dmac and attr.vlan_id. This patch sets attr.dmac and attr.vlan_id to zero.
