Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: fix endian lossage in forcedeth net/tokenring/olympic.c section fixes net: marvell.c fix sparse shadowed variable warning [VLAN]: Fix egress priority mappings leak. [TG3]: Add PHY workaround for 5784 [NET]: srandom32 fixes for networking v2 [IPV6]: Fix refcounting for anycast dst entries. [IPV6]: inet6_dev on loopback should be kept until namespace stop. [IPV6]: Event type in addrconf_ifdown is mis-used. [ICMP]: Ensure that ICMP relookup maintains status quo
