From c67f5db82027ba6d2ea4ac9176bc45996a03ae6a Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Thu, 17 Mar 2016 15:44:00 +0100 Subject: [PATCH] virtio_net: replace netdev_alloc_skb_ip_align() with napi_alloc_skb() This gives small but noticeable rx performance improvement (2-3%) and will allow exploiting future napi improvement.
