Allow the modification of whether or not we will allow BUM flooding on the vxlan bridge. To do this allow the upper level protocol to specify via the ZEBRA_VXLAN_FLOOD_CONTROL zapi message. If flooding is disabled then BUM traffic will not be forwarded to other VTEP's. Signed-off-by: Vivek Venkatraman <vivek@cumulusnetworks.com> Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
