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@01D7CA75.76DF9EB0]
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:
