backporting dummynet's q_time change ? (svn 184414)

[Luigi Rizzo]

in your logmessage for the q_time change in dummynet
http://svn.freebsd.org/viewvc/base?view=revision&revision=184414

mentions an ABI change that would prevent backporting.

However, as far as I can tell, the kernel side of the change is
fully self-contained in the ip_dummynet module, and the only
side effect on an out-of-sync userland (/sbin/ipfw) is that
you would not be able to run "ipfw pipe show" -- but you
can still configure ipfw rules and pipes and tables without
problems.

It seems to me that the change is sufficiently useful to deserve
a MFC, and the side effects are negligible and do not prevent an
upgrade with the usual sequence (installkernel-reboot-installworld)

Any objection to an MFC ?

cheers
