From 92651940ab00dbe64722e908f70d816713d677b7 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 12 Sep 2008 16:29:34 -0700 Subject: pkt_sched: Add multiqueue scheduler support This patch is intended to add a qdisc to support the new tx multiqueue architecture by providing a band for each hardware queue. By doing this it is possible to support a different qdisc per physical hardware queue. This qdisc uses the skb->queue_mapping to select which band to place the traffic onto. It then uses a round robin w/ a check to see if the subqueue is stopped to determine which band to dequeue the packet from.
