I'm not exactly sure why we need this delay, but commit 9a0e544f05bf ("test: Improve test for NDP assigned prefix") broke the tests for me.

I think it's because the kernel (at least all the versions I'm testing with) might not mark an address as 'kernel_ra' right away, so the jq expression doesn't return any result when we check.

This will do the job, but I think we can do better. There's logic above this to explicitly wait for DAD which doesn't seem to be working. Having another look at it, I think that's just because the conditions I used are a bit sloppy. I'm about to send a patch which improves them, which I hope will fix the problem you're seeing.
