Subject: [net-next PATCH 5/7] mlx4: use napi_alloc_skb API to get SKB bulk allocations
Date: Fri, 04 Mar 2016 14:02:05 +0100	[thread overview]
Message-ID: <20160304130205.32651.4079.stgit@firesoul> (raw)
In-Reply-To: <20160304130054.32651.51776.stgit@firesoul>

Activate the bulk alloc API, simply by changing mlx4 from using
netdev_alloc_skb() to using napi_alloc_skb().
