This fixes a struct redefinition problem like this one:
================================
In file included from /usr/include/linux/if_tunnel.h:6:0,
from iptunnel.c:34:
/usr/include/linux/ip.h:85:8: error: redefinition of 'struct iphdr'
struct iphdr {
^
In file included from iptunnel.c:29:0:
/usr/include/netinet/ip.h:45:8: note: originally defined here
struct iphdr
^
================================
iptunnel.c includes netinet/ip.h which contains a definition of the
iphdr struct.
iptunnel.c also includes linux/if_tunnel.h which includes linux/ip.h
which contains a definition of the iphdr struct.
So, both netinet/ip.h and linux/ip.h define the iphdr struct, and both
of them have been included directly or indirectly by iptunnel.c. Because
of that the compilation fails due to a struct redefinition.
The problem can be solved by just not including netinet/ip.h.
The patch has been sent upstream as a merge request:

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
