Subject: [PATCH 04/13] via-velocity: use netdev_alloc_skb

From: Stephen Hemminger <[email-masked]>
Date: Wed, 16 Apr 2008 16:37:31 -0700

Use netdev_alloc_skb for rx buffer allocation. This sets skb->dev
and can be overriden for NUMA machines.

Change code to return new buffer rather than call by reference.

Compile tested only!
