From 033d899904792d3501b7dd469495ca9138424ec3 Mon Sep 17 00:00:00 2001 From: Asim Shankar <asimshankar@gmail.com> Date: Tue, 3 May 2005 14:39:33 -0700 Subject: [PKT_SCHED]: HTB: Drop packet when direct queue is full htb_enqueue(): Free skb and return NET_XMIT_DROP if a packet is destined for the direct_queue but the direct_queue is full. (Before this: erroneously returned NET_XMIT_SUCCESS even though the packet was not enqueued) Signed-off-by: Asim Shankar <asimshankar@gmail.com> Signed-off-by: David S.
