Subject: [PATCH] net/ice: fix link status error when dev start
Date: Wed, 23 Nov 2022 12:42:13 +0000	[thread overview]
Message-ID: <1669207333-8769-1-git-send-email-hanshuang87@gmail.com> (raw)

ice_link_update get port link status and wait for one second when dev start.
If the device need almost one second for link up,
ice_link_update will enter the last rte_delay_ms(CHECK_INTERVAL) with link down,
in the meantime link interrupt raised,
the interrupt handler update dev->data->dev_link to up.
After a while the rte_delay_ms(CHECK_INTERVAL) finished
and update dev->data->dev_link to down.
