[NET]: Fix MAX_HEADER setting.
MAX_HEADER is either set to LL_MAX_HEADER or LL_MAX_HEADER + 48, and this is controlled by a set of CONFIG_* ifdef tests. It is trying to use LL_MAX_HEADER + 48 when any of the tunnels are enabled which set hard_header_len like this: dev->hard_header_len = LL_MAX_HEADER + sizeof(struct xxx); The correct set of tunnel drivers which do this are: ipip ip_gre ip6_tunnel sit so make the ifdef test match. Noticed by Patrick McHardy and with help from Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>
