Subject: [PATCH net-next V1 10/13] net/mlx5e: Use napi_alloc_skb for RX SKB allocations
Date: Wed, 16 Mar 2016 08:41:18 +0200 [thread overview]
Message-ID: <1458110481-18080-11-git-send-email-saeedm@mellanox.com> (raw)
In-Reply-To: <1458110481-18080-1-git-send-email-saeedm@mellanox.com>
From: Tariq Toukan <tariqt@mellanox.com>
Instead of netdev_alloc_skb, we use the napi_alloc_skb function
which is designated to allocate skbuff's for RX in a
channel-specific NAPI instance.
