From d6085e3ace20bc9b0fa625d8d79b22668710e217 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 20 Feb 2014 12:14:07 +0100 Subject: net: remove implicit peer from offload API The virtio_net offload APIs are used on the NIC's peer (i.e. the tap device). The API was defined to implicitly use nc->peer, saving the caller the trouble. This wasn't ideal because: 1. There are callers who have the peer but not the NIC. Currently they are forced to bypass the API and access peer->info->... directly. 2. The rest of the net.h API uses nc, not nc->peer, so it is inconsistent. This patch pushes nc->peer back up to callers.
