Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (1232 commits) iucv: Fix bad merging. net_sched: Add size table for qdiscs 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. ...
