vxlan: T5668: add CLI knob to enable ARP/ND suppression
In order to minimize the flooding of ARP and ND messages in the VXLAN network, EVPN includes provisions [1] that allow participating VTEPs to suppress such messages in case they know the MAC-IP binding and can reply on behalf of the remote host. In Linux, the above is implemented in the bridge driver using a per-port option called "neigh_suppress" that was added in kernel version 4.15. [1] https://www.rfc-editor.org/rfc/rfc7432#section-10
