There is an off by one error in interface.c of iw that prevents
passing of the cook flag when creating a monitor interface. The fix is
simple:

FWIW, I think I like "x <= Y" instead of "x < Y + 1".
Also, please make sure you are following the guidelines explained here:
http://linux.yyz.us/patch-format.html
In particular, I need a Signed-off-by line from you.
Thanks!
