This is know and fixed. The fix is to include linux/types.h
in serial.h.

Herbert added an include of ip.h in commit:

gre: Add netlink interface

This patch adds a netlink interface that will eventually displace
the existing ioctl interface. It utilises the elegant rtnl_link_ops

This causes struct iphdr to be redefined.
But there is noting wrong in including ip.h in if_tunnel.h.

I checked the include guards and they are correct.

Could you please investige where it picks up the first definition
of struct iphdr.

Anything that can improve the exported user headers are useful - thanks.
