Miller" <davem@...emloft.net>, Sasha Levin <Alexander.Levin@...rosoft.com> Subject: [PATCH AUTOSEL for 4.9 045/293] vxlan: dont migrate permanent fdb entries during learn From: Roopa Prabhu <roopa@...ulusnetworks.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.
