Add skb_warn_if_lro() to test whether an skb was received with LRO and
warn if so.

Change br_forward(), ip_forward() and ip6_forward() to call
skb_warn_if_lro() and discard the skb if it returns true.

This skb_is_gso() test should be inline.

So, instead make this something like:

include/linux/skbuff.h:

extern bool __skb_warn_if_lro(const struct sk_buff *skb);

static inline bool skb_warn_if_lro(const struct sk_buff *skb)
{
	if (unlikely(skb_is_gso(skb)))
		return __skb_warn_if_lro(skb);
	return false;
}

net/core/skbuff.c:

bool skb_warn_if_lro(const struct sk_buff *skb)
{
	if (net_ratelimit())
		pr_warning("%s: received packets cannot be forwarded"
			   " while LRO is enabled\n", skb->dev->name);
	return true;
}

Can you make this correction and resubmit this patch?

The second one looks fine to me, you don't need to resubmit
that one.

Thanks!
