Does the following steps make difference?
1. disable IPv6 (remove "options INET6) and IPsec, and
2. change the value of MINCLSIZE from (MHLEN + 1) to (MHLEN + MLEN + 1)
3. build a new kernel
4. try the same test
Due to mbuf simplification in IPv6 code (*), 1.4[A-Z] frequently
allocates cluster mbuf than before. If this bites people, I'll need
to switch IPv6 code to new mbuf manipulation framework (m_pulldown,
I have been testing m_pulldown in KAME code, and is working just fine
for me. I thought of testing it a bit more longer locally, but if
this fixes the problem, I'll bring it in sooner.
(*) m_pullup is not suitable for IPv6 traffic, due to bigger headers
and chained headers.
