s390/qeth: support GRO flush timer

julianwiedmann · davem330 · commit 978759e8266d · 2017-10-20T13:11:05.000+01:00
Switch to napi_complete_done(), and thus enable delayed GRO flushing.
The timeout is configured via /sys/class/net/&lt;if&gt;/gro_flush_timeout.

Default timeout is 0, so no change in behaviour.
