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

* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: (24 commits)
  [IPSEC]: Add xfrm_sysctl.txt.
  [BRIDGE]: Round off STP perodic timers.
  [BRIDGE]: Reduce frequency of forwarding cleanup timer in bridge.
  [TCP] tcp_probe: use GCC printf attribute
  [TCP] tcp_probe: a trivial fix for mismatched number of printl arguments.
  [IPV6] ADDRCONF: Fix conflicts in DEVCONF_xxx constant.
  [NET] napi: Call __netif_rx_complete in netif_rx_complete
  [TCP]: Consolidate checking for tcp orphan count being too big.
  [SOCK]: Shrink struct sock by 8 bytes on 64-bit.
  [AF_PACKET]: Kill CONFIG_PACKET_SOCKET.
  [IPV6]: Fix build warning.
  [AF_PACKET]: Kill bogus CONFIG_PACKET_MULTICAST
  [IPV4]: Kill references to bogus non-existent CONFIG_IP_NOSIOCRT
  [IPSEC]: Fix panic when using inter address familiy IPsec on loopback.
  [NET]: parse ip:port strings correctly in in4_pton
  [IPV6] ROUTE: No longer handle ::/0 specially.
  [IPSEC]: Fix IPv6 AH calculation in outbound
  [XFRM]: xfrm_larval_drop sysctl should be __read_mostly.
  [XFRM]: Allow XFRM_ACQ_EXPIRES to be tunable via sysctl.
  [CASSINI]: Fix printk message typo.
