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:
  [TIPC]: Add tipc_config.h to include/linux/Kbuild.
  [WAN]: lmc_ioctl: don't return with locks held
  [SUNRPC]: fix rpc debugging
  [TCP]: Saner thash_entries default with much memory.
  [SUNRPC] rpc_rdma: we need to cast u64 to unsigned long long for printing
  [IPv4] SNMP: Refer correct memory location to display ICMP out-going statistics
  [NET]: Fix error reporting in sys_socketpair().
  [NETFILTER]: nf_ct_alloc_hashtable(): use __GFP_NOWARN
  [NET]: Fix race between poll_napi() and net_rx_action()
  [TCP] MD5: Remove some more unnecessary casting.
  [TCP] vegas: Fix a bug in disabling slow start by gamma parameter.
  [IPVS]: use proper timeout instead of fixed value
  [IPV6] NDISC: Fix setting base_reachable_time_ms variable.
