>=20
> When iavf send query-stats command in eal-intr-thread through virtual
> channel, there will be no response received from iavf_dev_virtchnl_handle=
r
> for this command during block and wait.
> Because iavf_dev_virtchnl_handler is also registered in eal-intr-thread.
>=20
> When vf device is bonded as BONDING_MODE_TLB mode, the slave device
> update callback will registered in alarm and called by eal-intr-thread, i=
t would
> also raise the above issue.
>=20
> This commit add to poll the response for VIRTCHNL_OP_GET_STATS when it
> is called by eal-intr-thread to fix this issue.
