commit bbec7802c6948c8626b71a4fe31283cb4691c358 upstream.
vxlan driver has bypass for local vxlan traffic, but that depends on information about all VNIs on local system in vxlan driver. This is not available in case of LWT. Therefore following patch disable encap bypass for LWT vxlan traffic.
Fixes: ee122c79d42 ("vxlan: Flow based tunneling"). Reported-by: Jakub Libosvar jlibosva@redhat.com Signed-off-by: Pravin B Shelar pshelar@ovn.org Acked-by: Jiri Benc jbenc@redhat.com Signed-off-by: David S. Miller davem@davemloft.net Signed-off-by: Greg Kroah-Hartman gregkh@linuxfoundation.org
