Hi Xavier, As far as I can see the 'link_update' dev_ops (hns3_dev_link_update()), is just copying data from internal structure to "struct rte_eth_link". And you have timers set to regularly (ever second?) update the internal structure for link status. Instead, unless you are not using or need those status internally, you can pull the internal link status in the 'hns3_dev_link_update()', this way it can be possible to get rid of the timers. Also in current implementation, when used asked for the link status, it can be outdated regarding the status of the timers. In this patch, interrupt seems used to update the internal link status, this fixes the problem above that user is getting out of date link status. But instead of this, what do you think updating "struct rte_eth_link" too in the interrupt handler and advertising 'RTE_ETH_DEV_INTR_LSC' capability ("Link status event" feature in .ini file), so user can enable the lsc interrupt ('dev_conf.intr_conf.lsc') and gets the link status quicker because of the support in the API ('rte_eth_link_get')?

And in some extreme cases, this way is not faster than existing method regularly updating link status by issing the command every second in PF driver, because of the parallel processing of mailbox and command messages in firmware. So we reserve updating link status using timers in PF driver and don't advertising 'RTE_ETH_DEV_INTR_LSC' capability. And we will add querying link status by issuing command to the firmware in '.link_update' ops implementation function named hns3_dev_link_update to solve the out of date link status in patch V2.
