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: [NETFILTER]: nf_conntrack_pptp: fix NAT setup of expected GRE connections [NETFILTER]: nf_nat_pptp: fix expectation removal [NETFILTER]: nf_nat: fix ICMP translation with statically linked conntrack [TCP]: Restore SKB socket owner setting in tcp_transmit_skb(). [AF_PACKET]: Check device down state before hard header callbacks. [DECNET]: Handle a failure in neigh_parms_alloc (take 2) [BNX2]: Fix 2nd port's MAC address. [TCP]: Fix sorting of SACK blocks. [AF_PACKET]: Fix BPF handling. [IPV4]: Fix the fib trie iterator to work with a single entry routing tables
