Julian Wiedmann e8e99acd08 s390/qeth: schedule TX NAPI on QAOB completion ... [ Upstream commit 3e83d467a0 ] When a QAOB notifies us that a pending TX buffer has been delivered, the actual TX completion processing by qeth_tx_complete_pending_bufs() is done within the context of a TX NAPI instance. We shouldn't rely on this instance being scheduled by some other TX event, but just do it ourselves. qeth_qdio_handle_aob() is called from qeth_poll(), ie. our main NAPI instance. To avoid touching the TX queue's NAPI instance before/after it is (un-)registered, reorder the code in qeth_open() and qeth_stop() accordingly.
