Subject: [PATCH net] ibmveth: Do not process frames after calling napi_reschedule
Date: Thu, 24 Jan 2019 11:17:01 -0600	[thread overview]
Message-ID: <1548350221-8512-1-git-send-email-tlfalcon@linux.ibm.com> (raw)

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.
