Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6 

* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6:
  [TG3]: Add missing unlock in tg3_open() error path.
  [IPV6]: Fix address/interface handling in UDP and DCCP, according to the scoping architecture.
  [IRDA]: Lockdep fix.
  [BLUETOOTH]: Fix unaligned access in hci_send_to_sock.
  [XFRM]: nlmsg length not computed correctly in the presence of subpolicies
  [XFRM]: Sub-policies broke policy events
  [IGMP]: Fix IGMPV3_EXP() normalization bit shift value.
  [Bluetooth] Ignore L2CAP config requests on disconnect
  [Bluetooth] Always include MTU in L2CAP config responses
  [Bluetooth] Check if RFCOMM session is still attached to the TTY
  [Bluetooth] Handling pending connect attempts after inquiry
  [Bluetooth] Attach low-level connections to the Bluetooth bus
  [IPV6] IP6TUNNEL: Add missing nf_reset() on input path.
  [IPV6] IP6TUNNEL: Delete all tunnel device when unloading module.
  [IPV6] ROUTE: Do not enable router reachability probing in router mode.
  [IPV6] ROUTE: Prefer reachable nexthop only if the caller requests.
  [IPV6] ROUTE: Try to use router which is not known unreachable.
