From b89f04c61efe3b7756434d693b9203cc0cce002e Mon Sep 17 00:00:00 2001 From: Chonggang Li Date: Sun, 16 Apr 2017 12:02:18 -0700 Subject: [PATCH] bonding: deliver link-local packets with skb->dev set to link that packets arrived on MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bonding driver changes the skb->dev to the bonding-master before passing the packet to stack for further processing. This, however does not make sense for the link-local packets and it loses "the link info" once its skb->dev is changed to bonding-master. This patch changes this behavior for link-local packets by not changing the skb->dev to the bonding-master and maintaining it as it is, i.e. the link on which the packet arrived.
