Merge branch 'mptcp-out-of-order-queue-pruning'
Matthieu Baerts says:
====================
mptcp: out-of-order queue pruning
Under memory pressure, a pruning of the MPTCP-level OoO queue might be
required as last resort, to avoid too long recoveries, or even stalls.
Geliang and Gang managed to reproduce this behaviour, and Paolo
improved the situation thanks to the following patches:
- Patches 1-3: improve the MPTCP-level retransmission schema to make
recoveries from memory pressure/after MPTCP-level drop significantly
faster.
- Patches 4-5: make the admission check way stricter for incoming
packets exceeding the memory limits, with some exceptions for fallback
sockets.
- Patches 6-7: implement OoO queue pruning for MPTCP.
