If anyone has any objections, please let me know. ------------------ From: Roopa Prabhu [ 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") Signed-off-by: Roopa Prabhu Signed-off-by: David S.
