Subject: [PATCH 2.6.11.7] sch_htb: Drop packet when direct queue is full
Date: Thu, 21 Apr 2005 18:02:55 -0500 [thread overview]
Message-ID: <7bca1cb505042116022f64a87e@mail.gmail.com> (raw)
In-Reply-To: <20050421215440.GL577@postel.suug.ch>
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)
