[dpdk-dev] [PATCH v2] net/ice: fix link up when starting the device

[Yunjian Wang]

Currently, there is a possibility that the link status is not correct
after set link up, the device ID is 159b. It would be fixed by calling
ice_link_update() while the parameter 'wait_to_complete' is true. It's
reasonable to wait for complete right after set link up as it is not
in an link status change interrupt handling scenario.
