From e95d22c69b2c130ccce257b84daf283fd82d611e Mon Sep 17 00:00:00 2001 From: Thomas Falcon Date: Thu, 24 Jan 2019 11:17:01 -0600 Subject: [PATCH] ibmveth: Do not process frames after calling napi_reschedule 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. Signed-off-by: Thomas Falcon Signed-off-by: David S.
