* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: [IPSEC]: Fix the address family to refer encap_family [IPSEC]: changing API of xfrm6_tunnel_register [IPSEC]: make sit use the xfrm4_tunnel_register [IPSEC]: Changing API of xfrm4_tunnel_register. [TCP]: Prevent pseudo garbage in SYN's advertized window [NET_SCHED]: sch_hfsc: replace ASSERT macro by WARN_ON [BRIDGE] br_if: Fix oops in port_carrier_check [NETFILTER]: Clear GSO bits for TCP reset packet [TG3]: Update copyright, version, and reldate. [TG3]: Add some tx timeout debug messages. [TG3]: Use constant for PHY register 0x1e. [TG3]: Power down 5704 serdes transceiver when shutting down. [TG3]: 5906 doesn't need to switch to slower clock. [TG3]: 5722/5756 don't need PHY jitter workaround. [TG3]: Use lower DMA watermark for 5703. [TG3]: Save MSI state before suspend. [XFRM]: Fix IPv4 tunnel mode decapsulation with IPV6=n [IPV6] HASHTABLES: Use appropriate seed for caluculating ehash index.
