Hi,
In the Chicago meeting, I remember Joseph mentioned an issue on linux which
close all subflows that use an IP address when rem addr for it has been
received.

(page 13 in https://www.ietf.org/proceedings/98/slides/slides-98-mptcp-
sessa-channel-bonding-of-low-rate-links-using-mptcp-for-
airborne-flight-research-00.pdf)

As far as I read 6824bis draft, this behavior seems not to be recommended.
But, do we need more specific guidance here?

Thanks,
