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: (235 commits) [NETFILTER]: Add H.323 conntrack/NAT helper [TG3]: Don't mark tg3_test_registers() as returning const. [IPV6]: Cleanups for net/ipv6/addrconf.c (kzalloc, early exit) v2 [IPV6]: Nearly complete kzalloc cleanup for net/ipv6 [IPV6]: Cleanup of net/ipv6/reassambly.c [BRIDGE]: Remove duplicate const from is_link_local() argument type. [DECNET]: net/decnet/dn_route.c: fix inconsequent NULL checking [TG3]: make drivers/net/tg3.c:tg3_request_irq() static [BRIDGE]: use LLC to send STP [LLC]: llc_mac_hdr_init const arguments [BRIDGE]: allow show/store of group multicast address [BRIDGE]: use llc for receiving STP packets [BRIDGE]: stp timer to jiffies cleanup [BRIDGE]: forwarding remove unneeded preempt and bh diasables [BRIDGE]: netfilter inline cleanup [BRIDGE]: netfilter VLAN macro cleanup [BRIDGE]: netfilter dont use __constant_htons [BRIDGE]: netfilter whitespace [BRIDGE]: optimize frame pass up [BRIDGE]: use kzalloc ...
