[MPTCP] [PATCH v3 mptcp-next 0/4] mptcp: re-enable snd buf autotune

[Paolo Abeni <pabeni at redhat.com>]

WRT to the previous iteration, this clean-up patch 2/4 dropping the
left over 'use_backup' field, as suggested by Mat. No other change 

Relevant bits from the previous cover letter:

There are still some sporadic self-test failures for assimetric links.
Looks like they are caused by retransmissions/receiver dropping packets
due to MPTCP level OoO check.

I'll try to address that asap, but I still consider this series for
inclusion, so that it can stage a bit in the export branch.

Note: the last patch re-introduces the workqueue usage for the datapath (yes,
it makes me feel sick, sad and tired :(. I was unable to avoid it.


Paolo Abeni (4):
  mptcp: always graft subflow socket to parent.
  mptcp: re-enable sndbuf autotune
  mptcp: do not queue excessive data on subflows.
  mptcp: schedule work for better snd subflow selection
