[lwip-devel] [bug #52937] raw_input() must tell ip4/6_input() whether this protocol has been received

[Simon Goldschmidt]

Follow-up Comment #13, bug #52937 (project lwip):

Let's talk about what we want to achieve, not how.
- 'eaten' means 'delivered', 'packet handled' and 'pbuf freed'
- 'delivered' means the ip protocol has been matched. This suppresses ICMP for
unknown protocols but does not prevent pbufs for tcp, udp or igmp etc being
delivered to the real protocol stack

This patch seems to fix unknown ip protocols only. There's nothing wrong with
that. It doesn't mean any other change. We should have a separate discussion
whether changes to the raw recv callback are required.

I'd still favour a return code over an additional argument though.
