Hello all,

Looking at the api help for rte_eth_dev_set_link_up, it seems it is not 
required to call this function after rte_eth_dev_start. I see this 
confirmed in the fact that even not all pmds implement this function 
(e.g. virtio) and that some pmds call the link_up function in their 
start function.

However I am a bit confused by this example code:


in which there is a call to rte_eth_dev_set_link_up after the start.

In what cases is it needed to call rte_eth_dev_set_link_up right after
