[lwip-devel] [task #6861] Pimp ip_frag.c

[Jonathan Larmour]

Follow-up Comment #5, task #6861 (project lwip):

Good, I got permission. I'm attaching the fragmentation patch against 1.1. It
does not presently apply cleanly against CVS and I haven't updated it, but
you're going to be changing even more stuff in this area anyway.

If pbuf_alloc fails, the packet is simply dropped, with ERR_MEM.

The following was what I added to opt.h:
-=-=-=-=-=-=-=-=-=-=-=-=-
/* Use a static MTU-sized buffer for IP fragmentation.
 * Otherwise pbufs are allocated and reference the original
 * packet data to be fragmented.
 */
#ifndef IP_FRAG_USES_STATIC_BUF
#define IP_FRAG_USES_STATIC_BUF         0
#endif

/* Assumed max MTU on any interface for IP frag buffer */
#if IP_FRAG_USES_STATIC_BUF && !defined(IP_FRAG_MAX_MTU)
#define IP_FRAG_MAX_MTU                 1500
#endif
-=-=-=-=-=-=-=-=-=-=-=-=-
