Adding blue to pf

[Lennart Franked]

Hi

Me and a friend are currently working on a project where we are trying
to use the blue algorithm with pf.
We are using FreeBSD 6.1 Release and we've got pf working with RED.
However, adding the ALTQ_BLUE option to our kern conf seems to suggest
that the blue algorithm is not included out of the box.
Does anyone know if this is achievable in some way?

Thanks in advance.
