From 6ac644a8ae2dabf884a1b01e82e32d96ffe6eee5 Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Wed, 7 Oct 2015 16:47:32 -0700 Subject: sch_hhf: fix return value of hhf_drop() Similar to commit c0afd9ce4d6a ("fq_codel: fix return value of fq_codel_drop()") ->drop() is supposed to return the number of bytes it dropped, but hhf_drop () returns the id of the bucket where it drops a packet from.
