Bug Description

when a vxlan interface is created in linuxbridge agent, it is set with the argument "proxy" (ie "ip link add vxlan1 type vxlan id 1 dev wlan0 proxy group 224.0.0.1"), which means that it uses an arp-proxy. This should only be done when L2-population is activated, otherwise it leads to unaccessibility between vm that are note hosted on the same host.

    use proxy mode on vxlan interface only when l2-population is activated

    the proxy mode was set by default on every vxlan interfaces
    which leads to inaccessibility between VM that are not hosted
    on the same host in a vxlan network
