There was some discussion about this involving Marko Zec,  Adrian Chadd,
and myself
starting in this thread:

http://lists.freebsd.org/pipermail/svn-src-all/2013-July/071798.html

Adrian and Marko converged on similar patches:

http://lists.freebsd.org/pipermail/freebsd-hackers/2012-November/041120.html
http://people.freebsd.org/~adrian/ath/20130712-vimage-default-attach-detach.diff


As Marko mentioned in another e-mail on this thread, the patch as it is
necessary in
order to fix VIMAGE related kernel panics in many different scenarios,
including
ones involving Netgraph nodes.
