MQ Patch.

[Randall Stewart]

A quick follow up note.

I will have an update to this.. it looks like in
my build-universe I see if_var.h changed (includes and such) so
I will have to touch up drbr.h  (nothing like trying to hit a moving
target :-D)

I will send out an update after my build-universe completes (hopefully today).. but
take a look at this one anyway (understand a couple of includes and such may change) :-)
