zebra: VNI and VTEP handling Implement fundamental handling for VNIs and VTEPs: - Handle EVPN enable/disable by client (advertise-all-vni) - Create/update/delete VNIs based on VxLAN interface events and inform client - Handle VTEP add/delete from client and install into kernel - New debug command for VxLAN/EVPN - kernel interface (Linux/netlink only) Signed-off-by: Vivek Venkatraman <vivek@cumulusnetworks.com> Reviewed-by: Donald Sharp <sharpd@cumulusnetworks.com>

zebra: MAC and Neighbor (ARP/ND) handling Implement handling of MACs and Neighbors (ARP/ND entries) in zebra: - MAC and Neighbor database handlers - Read MACs and Neighbors from the kernel, when needed and create entries in zebra's MAC and Neighbor databases. - Handle add/update/delete notifications from the kernel for MACs and Neighbors and update zebra's database appropriately - Inform locally learnt MACs and Neighbors to client - Handle MACIP add/delete from client and install appriporiate entries into the kernel - Since Neighbor entries will be installed on an SVI, implement the needed mappings NOTE: kernel interface is only implemented for Linux/netlink Signed-off-by: Vivek Venkatraman <vivek@cumulusnetworks.com> Reviewed-by: Donald Sharp <sharpd@cumulusnetworks.com>
