Subject: [PATCH 4.9 23/32] ibmveth: Do not process frames after calling napi_reschedule
Date: Mon, 4 Mar 2019 09:22:11 +0100 [thread overview]
Message-ID: <20190304081603.972053420@linuxfoundation.org> (raw)
In-Reply-To: <20190304081602.307094059@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit e95d22c69b2c130ccce257b84daf283fd82d611e ]
The IBM virtual ethernet driver's polling function continues
to process frames after rescheduling NAPI, resulting in a warning
if it exhausted its budget. Do not restart polling after calling
napi_reschedule. Instead let frames be processed in the following
instance.
