[Devel] [PATCH vz10 1/4] ms/selftests: mptcp: join: rm: set backup flag

[Konstantin Khorenko]

> Some of these 'remove' tests rarely fail because a subflow has been
> reset instead of cleanly removed. This can happen when one extra subflow
> which has never carried data is being closed (FIN) on one side, while
> the other is sending data for the first time.
> 
> To avoid such subflows to be used right at the end, the backup flag has
> been added. With that, data will be only carried on the initial subflow.
