Subject: [PATCH net-next-2.6 9/9] sctp: move chunk from retransmit queue to abandoned list
Date: Wed, 20 Apr 2011 15:32:28 +0800 [thread overview]
Message-ID: <4DAE8C0C.8090506@cn.fujitsu.com> (raw)
In-Reply-To: <4DAE8A27.3040007@cn.fujitsu.com>
If there is still data waiting to retransmit and remain in
retransmit queue, while doing the next retransmit, if the
chunk is abandoned, we should move it to abandoned list.
