[TG3]: 40-bit DMA workaround part 2
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.
