Supposedly, the dual FIFO queue must be there for LLQ over frame relay
to work. However, adding FRF really damaged our call quality and we had
much better results without it.

I didn't get dual-fifo on my serial, with either a frf.12 nor
frame-relay
traffic-shaping and I have 12.2.6a. I have seen dual-fifo though
