I just noticed Davide had added support for changing the backup flag in
iproute2-next, so my patch "[PATCH iproute2-next 3/3] mptcp: add the
backup flag setting" needs to be dropped.

Furthermore, Davide's patch used 'change id $id backup' instead of 'set
$addr backup'. So this squash-to patch is needed.

pm_nl_set_endpoint is renamed to pm_nl_change_endpoint in this patch, so
please rename the subject too:

 Subject: selftests: mptcp: implement pm_nl_change_endpoint

I did include this patch when reviewing the "use 'ip mptcp' in selftests" 
series. It's good to squash, waiting on discussion of one question in 
patch 7/9
