Hash Suite for Android: free password hash cracker in your pocket
[<prev] [next>] [thread-next>] [day] [month] [year] [list]
Message-ID: <1269961335.2012.66.camel@edumazet-laptop>
Date:	Tue, 30 Mar 2010 17:02:15 +0200

Subject: [PATCH net-next] net: remove redundant code

eth_type_trans(skb, netdev) does the "skb->dev = netdev;"
initialization, we can remove it from various network drivers.
