Subject: [PATCH net-next 25/26] vlan: link the upper neighbour only after registering
Date: Mon,  9 Sep 2013 22:16:43 +0200	[thread overview]
Message-ID: <1378757804-3159-26-git-send-email-vfalico@redhat.com> (raw)
In-Reply-To: <1378757804-3159-1-git-send-email-vfalico@redhat.com>

Otherwise users might access it without being fully registered, as per
sysfs - it only inits in register_netdevice(), so is unusable till it is
called.
