Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "A quick batch of bug fixes: 1) Fix build with IPV6 disabled, from Eric Dumazet. 2) Several more cases of caching SKB data pointers across calls to pskb_may_pull(), thus referencing potentially free'd memory. From Li RongQing. 3) DSA phy code tests operation presence improperly, instead of going: if (x->ops->foo) r = x->ops->foo(args); it was going: if (x->ops->foo(args)) r = x->ops->foo(args); Fix from Andew Lunn" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: Net: DSA: Fix checking for get_phy_flags function ipv6: fix a potential use after free in sit.c ipv6: fix a potential use after free in ip6_offload.c ipv4: fix a potential use after free in gre_offload.c tcp: fix build error if IPv6 is not enabled
