[dpdk-dev] [dpdk-users] A question about the link status of the intel E810 nic can not be up?

[wangyunjian]

Hi, All:

I am using Intel E810 with DPDK v21.11 to create a dpdkbond but there
is a probability that the failure will occur.

During the test, the bonding is repeatedly added and deleted. Sometimes,
the link status of the NIC is Down. And if call ice_dev_set_link_up again,
the link status of the NIC can be recovered. 

Alternatively, the problem can be avoided by modifying the ice pmd driver.
