* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: (36 commits)
  [Bluetooth] Fix HID disconnect NULL pointer dereference
  [Bluetooth] Add missing entry for Nokia DTL-4 PCMCIA card
  [Bluetooth] Add support for newer ANYCOM USB dongles
  [NET]: Can use __get_cpu_var() instead of per_cpu() in loopback driver.
  [IPV4] inet_peer: Group together avl_left, avl_right, v4daddr to speedup lookups on some CPUS
  [TCP]: One NET_INC_STATS() could be NET_INC_STATS_BH in tcp_v4_err()
  [NETFILTER]: Missing check for CAP_NET_ADMIN in iptables compat layer
  [NETPOLL]: initialize skb for UDP
  [IPV6]: Fix route.c warnings when multiple tables are disabled.
  [TG3]: Bump driver version and release date.
  [TG3]: Add lower bound checks for tx ring size.
  [TG3]: Fix set ring params tx ring size implementation
  [NET]: reduce per cpu ram used for loopback stats
  [IPv6] route: Fix prohibit and blackhole routing decision
  [DECNET]: Fix input routing bug
  [TCP]: Bound TSO defer time
  [IPv4] fib: Remove unused fib_config members
  [IPV6]: Always copy rt->u.dst.error when copying a rt6_info.
  [IPV6]: Make IPV6_SUBTREES depend on IPV6_MULTIPLE_TABLES.
  [IPV6]: Clean up BACKTRACK().
