Jesse Brandeburg e508be174a e1000: fix Tx hangs by disabling 64-bit DMA ... Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO.
