Subject: [PATCH net-next 4/4] selftests: fib_tests: sleep after changing carrier

From: David Ahern <[email-masked]>
Date: Tue, 13 Feb 2018 08:37:36 -0800

sleep for a second after setting carrier down to allow linkwatch
to propagate the change to the routing stack via netdev_state_change.
As it stands there is a race setting carrier down on the dummy
device and then checking the linkdown flag in the routes.
