ovs 源mac， 目的src 互换

 

push:NXM_OF_ETH_SRC[],push:NXM_OF_ETH_DST[],pop:NXM_OF_ETH_SRC[],pop:NXM_OF_ETH_DST[]

 

1：把src mac推到栈顶

push:NXM_OF_ETH_SRC[]

 

2：把dst mac推到栈顶

push:NXM_OF_ETH_DST[]

 

3：从栈顶读取mac存到NXM_OF_ETH_SRC[]

pop:NXM_OF_ETH_SRC[]

 

4：从栈顶读取mac存到NXM_OF_ETH_DST[]

pop:NXM_OF_ETH_DST[]
