Do you mean in sfq.c - ie sfq_enqueue etc. Maybe you mean something else.

I don't know as such, but always assumed that when attached to HTB - a
packet gets enqueued if there aren't enough (c)tokens to send it and
dequeued when there are. As for timing I don't think sfq uses any - it's
up to whatever it is attached to.
sfq_drop is called from sfq_enqueue when the queue is full. It drops
from the longest slot.
requeue - don't know.
Andy.
