Thank Stephen, but in which the scenarios, it should wait link to up, in which scenarios, it should not ? By the way, how to define the "wait" time value ?

I know they call funciton "link_update" with differenct parameter "wait_to_complete"(set 1 means wait, set 0 means not wait). But how to define the "wait" time, and why it shoud wait? On the further, What are the application scenarios of the two APIs?The default behavior of rte_eth_link_get (in some drivers) is to wait for link to come up. Many drivers don't do this. It seems mostly the Intel ones that do. .
