tg3: Disable new DMA engine for 57766
A bug was found in the new DMA engine for the 57766. This patch disables it, which causes the device to fallback to the old DMA engine. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
