Message-Id: <1368768078-16121-2-git-send-email-linux@prisktech.co.nz>

Subject: [PATCHv6 1/3] net: velocity: Rename vptr->dev to vptr->netdev
Improve the clarity of the code in preparation for converting the
dma functions to generic versions, which require a struct device *.
This makes it possible to store a 'struct device *dev' in the
velocity_info structure.
