Subject: vxlan: dont migrate permanent fdb entries during learn
Patch-mainline: v4.13-rc1
Git-commit: e0090a9e979de5202c7d16c635dea2f005221073
References: bsc#1076830
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")
