I'm impressed that someone's using an IMP number, but I'd suggest
treating the field as a simple s_addr instead.

I would have expected:
len = sizeof (*v4hdr) + msgsize(m);
v4hdr->ip_len = htons(len);

Why not copy the TClass from the v6 header?

Handling v6 fragments is going to be interesting, I think.

This doesn't look right. Is this on SPARC or x86? Maybe what was
meant was:
v4hdr->ip_off = htons(IP_DF);

Look at "netstat -s" for errors. That'd be a fair place to start.
Try using the "mib" dtrace provider to locate where the packets are
dropping.
Read the source associated with the functions that dtrace identifies.
