Subject: Please help to see this DPDK problem//Reply: DPDK 20.11 - i40evf: No response for 14

BUG: DPDK-20.11- i40evf: No response for 14

Hi:
I am using Intel SR-IOV XL710 VF with DPDK v20.11 to create a dpdkbond but failed.
         [cid:image001.png@01D7CA79.73F04A20]
         As the picture shows, when dpdk bond start and slave link up, it triggers lsc callback function which registers in the eal thread, and then in the activate_slave process,
i40evf send msg 14 to pf to config promisc, but there is no response received. Because function "i40evf_handle_aq_msg" in which vf receives response from pf
is in the same thread of eal with function "_i40evf_execute_vf_cmd" in which vf sends msg to pf. Thus, when eal thread goes in function _i40evf_execute_vf_cmd,
it can't handle msg from pf at the same time, then it will report "No response for 14" in dpdk log.

And there are the error logs in dpdk:

According to the README at 
https://downloadmirror.intel.com/28381/eng/readme.txt you need to enable 
a VF as trusted for promiscuous mode.  Looks like this:

# ip link set dev eth0 vf 1 trust [on|off]

Did you enable the VF as trusted before assigning the NIC to the OVS switch?

I do enable the VF as trusted before assigning the NIC to the OVS switch. 
And we are about to release our commercial version with this feature, would you please to help me with this problem as soon as possible? 

Thank you,
Liao
