[PATCH net 0/3] selftests: mptcp: reduce bufferbloat and cleanup

From: Matthieu Baerts (NGI0)

Date: Wed May 27 2026 - 08:14:28 EST


Bufferbloat is baaaad, even in our selftests: let's kill it (or at least
reduce it). By doing that, the tests (seem to) have a more stable
transfer, and are then less unstable. That's what patches 1-2 are doing,
and they can be backported up to 5.10.

Patch 3 is not related: a small fix in the selftests to remove temp
files that were not deleted in some conditions, since v5.13.
