Jason Wang d71ebe8114 virtio-net: correctly enable callback during start_xmit ... Commit a7766ef18b33("virtio_net: disable cb aggressively") enables virtqueue callback via the following statement: do { if (use_napi) virtqueue_disable_cb(sq->vq); free_old_xmit_skbs(sq, false); } while (use_napi && kick && unlikely(!virtqueue_enable_cb_delayed(sq->vq))); When NAPI is used and kick is false, the callback won't be enabled here. And when the virtqueue is about to be full, the tx will be disabled, but we still don't enable tx interrupt which will cause a TX hang. This could be observed when using pktgen with burst enabled. TO be consistent with the logic that tries to disable cb only for NAPI, fixing this by trying to enable delayed callback only when NAPI is enabled when the queue is about to be full.
