Subject: [PATCH AUTOSEL 4.14 35/40] ibmveth: Do not process frames after calling napi_reschedule
Date: Thu, 14 Feb 2019 21:13:08 -0500 [thread overview]
Message-ID: <20190215021313.178476-35-sashal@kernel.org> (raw)
In-Reply-To: <20190215021313.178476-1-sashal@kernel.org>
From: Thomas Falcon <tlfalcon@linux.ibm.com>
[ 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.
