  net_sched: Add accessor function for packet length for qdiscs
  net_sched: Add qdisc_enqueue wrapper
  highmem: Export totalhigh_pages.
  ipv6 mcast: Omit redundant address family checks in ip6_mc_source().
  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
  ipv6: remove unused parameter from ip6_ra_control
  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
  sctp: Allow only 1 listening socket with SO_REUSEADDR
  sctp: Do not leak memory on multiple listen() calls
  sctp: Support ipv6only AF_INET6 sockets.
