  net: Use standard structures for generic socket address structures.
  ipv6 netns: Make several "global" sysctl variables namespace aware.
  netns: Use net_eq() to compare net-namespaces for optimization.
  ipv6: remove unused macros from net/ipv6.h

  tcp: fix kernel panic with listening_get_next
  tcp: Remove redundant checks when setting eff_sacks
  tcp: options clean up
  tcp: Fix MD5 signatures for non-linear skbs
  sctp: Update sctp global memory limit allocations.
  sctp: remove unnecessary byteshifting, calculate directly in big-endian
