Subject: [PATCH net v9 7/7] libcxgbi: fix freeing skb prematurely
Date: Thu, 11 Dec 2014 07:25:58 -0800 [thread overview]
Message-ID: <201412111525.sBBFPw0b012963@localhost6.localdomain6> (raw)
From: Karen Xie <kxie@chelsio.com>
With debug turned on the debug print would access the skb after it is freed.
Fix it to free the skb after the debug print.
