pasemi_mac: fix bug in receive buffer dma mapping
pasemi_mac: fix bug in receive buffer dma mapping skb->len isn't actually set to the size of the allocated skb, so don't try to use it when figuring out how much to map. (This hasn't surfaced as a real bug because we effectively disable translation for the interface, but it still needs fixing for the future) Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
