Hey Vladone,

I was looking for the same thing a while back, wanting to use ALTQ for
PF.  Enable support in the kernel by adding the following lines:

# ALTQ support
options         ALTQ
options         ALTQ_CBQ        # Class Bases Queuing (CBQ)
options         ALTQ_RED        # Random Early Detection (RED)
options         ALTQ_RIO        # RED In/Out
options         ALTQ_HFSC       # Hierarchical Packet Scheduler (HFSC)
options         ALTQ_PRIQ       # Priority Queuing (PRIQ)
options         ALTQ_NOPCC      # Required for SMP build

You may not need the NOPCC option, depends on your system.
