Subject: [dpdk-dev] [dpdk-users] A question about the link status of the intel E810 nic can not be up?
Date: Mon, 10 Jan 2022 03:20:14 +0000 [thread overview]
Message-ID: <41f0c2c9f77348fbb22dad35ef155536@huawei.com> (raw)
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.
