[lwip-devel] [bug #2942] pbuf_realloc cannot not grow chains (can only shrink chains).

Follow-up Comment #2, bug #2942 (project lwip):

binary size...

Well, I'd have to say since we don't have it now, and things are apparently
working okay, we must not really need it. ;)

The only real issue I see here is that pbuf_realloc() SOUNDS like it should
be able to construct a larger payload area... and it can't, hence the
well-documented shortcoming. Why bug #2942 was entered, I don't know... Did
Leon want this functionality for some specific purpose?

Perhaps simply renaming it from pbuf_realloc() to pbuf_trim() or something
along those lines would be sufficient to put this one to rest?
