Is there any reason why it wouldn't be possible to eliminate the MTU sized
buffer used by ip_frag.c? It seems to me that it would not be hard to
create a chain of pbufs of type PBUF_REF which have the payload pointing
directly into the payloads of the pbuf chain being sent. If no-one sees any
reason why this wouldn't work, I'll put this on my todo list, and I might
be able to do it in the context of my current project.
Secondly the configurability of ip_frag.c isn't great. I think both MAX_MTU
and IP_REASS_BUFSIZE are important values which should be settable options
from lwipopts.h - ip_frag.c takes 7374 bytes of RAM in total, ouch. While
we're there, there's also less important options such as IP_REASS_MAXAGE
and IP_REASS_TMO.
It's a simple enough patch for the latter. Do I just send patches here? I
should have more patches to come in due course.
