Ovs Bond 支持3种模式：balance-tcp（根据IP地址+TCP端口负载均衡），balance-slb(根据源MAC地址负载均衡)，active-backup(主备模式)。

网络类型	本端bond_mode	本端 LACP	对物理交换机 bond-mode	对端 LACP
vxlan   active-backup	Off	        不配 bond	
        balance-slb	Off	        不配 bond	
        Balance-tcp	Active	        必须配bond	        Active或者passive
vlan    Active-backup	Off	        不配 bond	
        Balance-slb	Off	        不配 bond	
        Balance-tcp	Active	        必须配bond	        Active 或者passive
