Miller" <davem@...emloft.net>, Sasha Levin <sashal@...nel.org>, linuxppc-dev@...ts.ozlabs.org, netdev@...r.kernel.org Subject: [PATCH AUTOSEL 4.19 58/65] ibmveth: Do not process frames after calling napi_reschedule From: Thomas Falcon <tlfalcon@...ux.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. Signed-off-by: Thomas Falcon <tlfalcon@...ux.ibm.com> Signed-off-by: David S.
