Subject: [PATCH net-next 2/8] s390/qeth: remove bogus netif_wake_queue()
Date: Fri, 25 Jan 2019 15:44:17 +0100 [thread overview]
Message-ID: <20190125144423.81443-3-jwi@linux.ibm.com> (raw)
In-Reply-To: <20190125144423.81443-1-jwi@linux.ibm.com>
qeth_qdio_cq_handler() doesn't replenish the Output Queue(s), and thus
has no reason to wake the txq.
