Subject: vxlan: dont migrate permanent fdb entries during learn

From: Roopa Prabhu <roopa@cumulusnetworks.com>


[ Upstream commit e0090a9e979de5202c7d16c635dea2f005221073 ]

This patch fixes vxlan_snoop to not move permanent fdb entries
on learn events. This is consistent with the bridge fdb
handling of permanent entries.
