You guys aren't making this troubleshooting any easier, you know.

I just stripped out m_defrag, and inserted m_collapse, to my newly
csupped RELENG_7.

RELENG_7 does contain m_collapse. At least, buildkernel complains
about it if i insert
it into if_re.c It probably hasn't been rfc'd to RELENG_7_0.

if_re.c is a different version, though. I'm using version 1.103.
