Subject: [PATCH] nss-dp: edma-v1: use NAPI GRO by default
|
||
|
|
|
||
|
|
Utilize napi_gro_receive instead of plain netif_receive_skb on EDMA v1.
|
||
|
|
|
||
|
|
Usually it provides quite a lot of RX speed improvements, however in some
|
||
|
|
cases it may lead to decreased performance as there is no checksum
|
||
|
|
offloading implemented.
|
||
|
|
|
||
|
|
In cases where reduced performance is experienced its possible to disable
|
||
|
|
GRO by using ethtool.
