PF driver and VF driver communicated with each other by virtual channel message. When VF sends message to PF to enable some offload capability, PF should response if it is successful or not. VIRTCHNL_OP_ENABLE_VLAN_STRIPPING is a new added message and the old PF driver doesn’t support that. So no response is received by DPDK VF. Then VF is blocked on this message and cannot roll back. This patch clears pending command on VF side when the waiting duration expires to avoid blocking following communication.
