From 27141666b69f535a4d63d7bc6d9e84ee5032f82a Mon Sep 17 00:00:00 2001 From: "Jorge Boncompte [DTI2]" Date: Mon, 16 Jun 2008 17:15:33 -0700 Subject: [PATCH] atm: [br2684] Fix oops due to skb->dev being NULL It happens that if a packet arrives in a VC between the call to open it on the hardware and the call to change the backend to br2684, br2684_regvcc processes the packet and oopses dereferencing skb->dev because it is NULL before the call to br2684_push().
