hi. I'm working with intel suport on this and they told me this is a known issue and that the only way to link down is via some debugfs commands...
echo "send aq_cmd" 0 0x601 0 0 0 0 0 0x00002000 0 0 > /sys/kernel/debug/i40e/0000\:04\:00.0/command
The problem now is that my debugs i40e directory is empty so I have to file to send the command to
any idea why debugfs directory is empty ?
Intel(R) 40-10 Gigabit Ethernet Connection Network Driver - version 1.5.25
I am sorry I do not have the information, so have you also check with Intel support about this?
For the meantime, let me check if there is any thing to share
