This brings (hopefully) the final bits required to address the
data transfer stall reported by Geliang and Gang 

Patch 1 is a mostly cosmetic change over a previously accepted patch,
while patch 2 and 3 improves mptcp retranmission to make them reliable:
pruning can require some of them.

The main change over the previous iteration is in patch 3, addressing
sashiko feedback over the previous iteration (missing timer reschedule
in some corner cases).

Paolo Abeni (3):
  Squash-to: "mptcp: implemented OoO queue pruning"
  mptcp: move the retrans loop to a separate helper
  mptcp: let the retrans scheduler do its job.

If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-normal

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)
