    [TG3]: 40-bit DMA workaround part 2 · 4a29cc2e
    Michael Chan authored
    The 40-bit DMA workaround recently implemented for 5714, 5715, and
    5780 needs to be expanded because there may be other tg3 devices
    behind the EPB Express to PCIX bridge in the 5780 class device.
    
    For example, some 4-port card or mother board designs have 5704 behind
    the 5714.
    
    All devices behind the EPB require the 40-bit DMA workaround.
    
    Thanks to Chris Elmquist again for reporting the problem and testing
    the patch.
