How to supress ALTQ warning?

[Miroslav Lachman]

Hi all,

I have PF as loadable module without ALTQ support because I do not use 
ALTQ. Every pfctl command emits warning to stderr:
-----
No ALTQ support in kernel
ALTQ related functions disabled
-----

Is there any option to supress this but only this warning message? (I am 
using pfctl in some shell scripts and I want see error messages, but not 
this one)

Thanks for your help.
