[OE-core] [PATCH] iproute2: backport a patch to make adding vxlan link success

[Iorga, Cristian]

Hi,
1. Patch has not been marked with Upstream-status indication.
2. An upgrade to iproute2 3.17 is due in a short amount of time.

If this is a burning issue, should be taken for inclusion; otherwise hold it to be included with the incoming upgrade.

Regards,
Cristian Iorga

If without this patch:
    $ ip link add vxlan0 type vxlan id 51 group 238.1.1.1 dev eth0
    Error: argument "vxlan0" is wrong: Unknown device
    $

With this patch;
    $ ip link add vxlan0 type vxlan id 51 group 238.1.1.1 dev eth0
    $ ifconfig -a |grep vxlan0
    vxlan0    Link encap:Ethernet  HWaddr da:61:56:2e:c2:20
    $

+Subject: [PATCH] ip link: Remove unnecessary device checking
+
+The real checking is performed later in iplink_modify(..) func which 
+checks device existence if NLM_F_CREATE flag is set.
+
+Also it fixes the case when impossible to add veth link which was 
+caused by 9a02651a87 (ip: check for missing dev arg when doing VF rate) 
+because these devices are not exist yet.
