ip link needs 'name' in 3.16 to create the veth pair

Due to a change (or bug?) in ip link implementation, the command
    'ip link add vnet0...'
is forced into
    'ip link add name vnet0...'
The changed command also works on older versions of iproute2, just the
'name' parameter has been made mandatory.
