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: (51 commits) [IPV6]: Fix again the fl6_sock_lookup() fixed locking [NETFILTER]: nf_conntrack_tcp: fix connection reopening fix [IPV6]: Fix race in ipv6_flowlabel_opt() when inserting two labels [IPV6]: Lost locking in fl6_sock_lookup [IPV6]: Lost locking when inserting a flowlabel in ipv6_fl_list [NETFILTER]: xt_sctp: fix mistake to pass a pointer where array is required [NET]: Fix OOPS due to missing check in dev_parse_header(). [TCP]: Remove lost_retrans zero seqno special cases [NET]: fix carrier-on bug? [NET]: Fix uninitialised variable in ip_frag_reasm() [IPSEC]: Rename mode to outer_mode and add inner_mode [IPSEC]: Disallow combinations of RO and AH/ESP/IPCOMP [IPSEC]: Use the top IPv4 route's peer instead of the bottom [IPSEC]: Store afinfo pointer in xfrm_mode [IPSEC]: Add missing BEET checks [IPSEC]: Move type and mode map into xfrm_state.c [IPSEC]: Fix length check in xfrm_parse_spi [IPSEC]: Move ip_summed zapping out of xfrm6_rcv_spi [IPSEC]: Get nexthdr from caller in xfrm6_rcv_spi [IPSEC]: Move tunnel parsing for IPv4 out of xfrm4_input ...
