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: [IPV4/IPV6]: Setting 0 for unused port field in RAW IP recvmsg(). [IPV4] ipmr: ip multicast route bug fix. [TG3]: Update version and reldate [TG3]: Handle tg3_init_rings() failures [TG3]: Add tg3_restart_hw() [IPV4]: Clear the whole IPCB, this clears also IPCB(skb)->flags. [IPV6]: Clean skb cb on IPv6 input. [NETFILTER]: Demote xt_sctp to EXPERIMENTAL [NETFILTER]: bridge netfilter: add deferred output hooks to feature-removal-schedule [NETFILTER]: xt_pkttype: fix mismatches on locally generated packets [NETFILTER]: SNMP NAT: fix byteorder confusion [NETFILTER]: conntrack: fix SYSCTL=n compile [NETFILTER]: nf_queue: handle NF_STOP and unknown verdicts in nf_reinject [NETFILTER]: H.323 helper: fix possible NULL-ptr dereference
