team: send port changed when added
On some hw, link is not up during adding iface to team. That causes event not being sent to userspace and that may cause confusion. Fix this bug by sending port changed event once it's added to team. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
