None of these are true anymore (hooray!).

 	We still need true WFQ for top level CSZ, but using WFQ
 	for the best effort traffic is absolutely pointless:
-	SFQ is superior for this purpose.
-
-	IMPLEMENTATION:
-	This implementation limits maximal queue length to 128;
-	maximal mtu to 2^15-1; number of hash buckets to 1024.
-	The only goal of this restrictions was that all data
-	fit into one 4K page :-). Struct sfq_sched_data is
-	organized in anti-cache manner: all the data for a bucket
-	are scattered over different locations. This is not good,
-	but it allowed me to put it into 4K.
-
-	It is easy to increase these values, but not in flight.  */
