| 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. |
| |
| Fixes: 26a41ae60438 ("vxlan: only migrate dynamic FDB entries") |
