From 29824310ce3e320726a45475a38fd0c3f0eaad60 Mon Sep 17 00:00:00 2001 From: Harry Mason Date: Fri, 17 Jan 2014 13:22:32 +0000 Subject: [PATCH] sch_htb: let skb->priority refer to non-leaf class If the class in skb->priority is not a leaf, apply filters from the selected class, not the qdisc. This lets netfilter or user space partially classify the packet. Signed-off-by: Harry Mason Acked-by: Eric Dumazet Signed-off-by: David S.
