Pablo Neira Ayuso says:

====================
The following batch contains:

* Three fixes for the new synproxy target available in your
  net-next tree, from Jesper D. Brouer and Patrick McHardy.

* One fix for TCPMSS to correctly handling the fragmentation
  case, from Phil Oester. I'll pass this one to -stable.
