Hi Dan, Ferruh,
Why do we need "struct rte_eth_link" as a parameter at all?
Only link status is used in the function – let's use it only:
rte_kni_update_link(struct rte_kni *kni, int link_status) /* 0 – down, 1 –
up */
It will also solve your differences as we won't have any "redundant"
information to print :)
Best regards,
Igor
