XL710 firmware do not work?

[CLi46]

Hi, All,

I assign XL710 VF to QEMU, and load modified i40evf driver in QEMU, then I encounter the following error in the qemu:

"Admin queue command never completed"

and get the following error log in host OS system:

[ 7823.295061] pci 0000:03:02.2: enabling device (0000 -> 0002)

Then I unload and reload i40e driver in host OS system and encouter the following error:

[ 7856.803922] i40e: Intel(R) Ethernet Connection XL710 Network Driver - version 0.4.21-k

[ 7857.034679] i40e: probe of 0000:03:00.0 failed with error -2

I debug the i40e driver code and found that the driver call i40evf_asq_send_command to get firmware and api version but the firmware did not write back any information (so the firmware and api version in the above message are both 0). After rebooting the host system, it works again. This problem happens from time to time, and I can't reproduce it at will.

Before unload and reload the i40e driver, I give the EMP reset command by execute "echo empr > /sys/kernel/debug/i40e/0000\:03\:00.0/command", but it did not fix the problem.

Dose anyone know why this happen and how to recover from the problem ? Thanks in advance!

I run on ubuntu 14.10 x86-64 with updated kernel 3.17.6-031706-generic.
