From af548a27b158d548d41e56255e6eaca1658cc3be Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Fri, 22 Feb 2019 07:27:41 -0300 Subject: selftests: fib_tests: sleep after changing carrier. again. Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.
