Not quite, no. The dropping of packets is based on actual calculations in
RED that aren't available in SFQ. SFQ drops _all_ the packets off the end
and doesn't start doing so before congestion happens -- RED is designed to
drop packets before getting overly congested so that the stream speeds stay
steady and don't try to climb above what's available.
