Subject: [PATCH net-next 11/12] ibmvnic: Use netdev_alloc_skb instead of alloc_skb to replenish RX buffers
Date: Thu, 12 Nov 2020 13:10:06 -0600	[thread overview]
Message-ID: <1605208207-1896-12-git-send-email-tlfalcon@linux.ibm.com> (raw)
In-Reply-To: <1605208207-1896-1-git-send-email-tlfalcon@linux.ibm.com>

From: "Dwip N. Banerjee" <dnbanerg@us.ibm.com>

Take advantage of the additional optimizations in netdev_alloc_skb when
allocating socket buffers to be used for packet reception.
