seems that commit e3b37f11e6e4e6b6 ("netfilter: replace list_head with
single linked list") breaks the build on !CONFIG_NETFILTER_INGRESS systems
accessing ->nf_hooks_ingress
static void nf_set_hooks_head(struct net *net, const struct nf_hook_ops *reg,
struct nf_hook_entry *entry)
{
switch (reg->pf) {
case NFPROTO_NETDEV:
/* We already checked in nf_register_net_hook() that this is
* used from ingress.
*/
rcu_assign_pointer(reg->dev->nf_hooks_ingress, entry);
