From aa8751667dcd757dd9a711b51140adf181501c44 Mon Sep 17 00:00:00 2001 From: Andrea Bittau Date: Sun, 20 Nov 2005 13:41:05 -0800 Subject: [PATCH] [PKT_SCHED]: sch_netem: correctly order packets to be sent simultaneously If two packets were queued to be sent at the same time in the future, their order would be reversed. This would occur because the queue is traversed back to front, and a position is found by checking whether the new packet needs to be sent before the packet being examined. If the new packet is to be sent at the same time of a previous packet, it would end up before the old packet in the queue. This patch places packets in the correct order when they are queued to be sent at a same time in the future. Signed-off-by: Andrea Bittau Signed-off-by: David S.
