gre: Compatibility with older Linux kernel versions. The upcoming GRE kernel module compiles on a range (2.6.18+) of Linux kernel versions. The module expects the kernel headers to look like newer versions.

Don't define "skb_dst_drop" if other skb_dst accessor funcs are defined When "skb_dst" is included in the kernel sources, don't redefine "skb_dst_drop", which is defined in dst.h. 2010-05-17 13:57:29 -07:00			`#ifndef HAVE_SKB_DST_ACCESSOR_FUNCS`
