1) Setting link attributes can modify the size of the attributes that
   would be reported on a subsequent getlink netlink operation,
   therefore min_ifinfo_dump_size needs to be adjusted.  From Stefan
   Gula.

2) Resegmentation of TSO frames while trimming can violate invariants
   expected by callers, namely that the number of segments can only stay
   the same or decrease, never increase.  If MSS changes, however, we
   can trim data but then end up with more segments.  Fix this by only
   segmenting to the MSS already recorded in the SKB.  That's the
   simplest fix for now and if we want to get more fancy in the future
   that's a more involved change.

   This probably explains some retransmit counter inaccuracies.

   From Neal Cardwell.

3) Fix too-many-wakeups in POLL with AF_UNIX sockets, from Eric Dumazet.

4) Fix CAIF crashes wrt.  namespace handling.  From Eric Dumazet and
   Eric W. Biederman.

5) TCP port selection fixes from Flavio Leitner.

6) More socket memory cgroup build fixes in certain randonfig
   situations.  From Glauber Costa.

7) Fix TCP memory sysctl regression reported by Ingo Molnar, also from
   Glauber Costa.
