* | tg3: Fix read DMA FIFO overruns on recent devicesMatt Carlson2010-09-151-1/+5
|/ | | | | | | | | | | | | | | | | Earlier versions of tg3 devices had a problem where the read DMA FIFO could be overrun in certain edge conditions. The fix was to limit the number of rx BDs the hardware would fetch at a time. For later devices (5761, 5784 and later ASIC revs), there is a hardware fix that must be enabled to fix the same problem. This patch adds that hardware fix. There is a gap in the ASIC revision lineage where neither fix is applied. This is intentional as these ASIC revisions are not afflicted by the bug.

| | | | | | | | | | | | | | | | | On a PCIX bus, the 5701 has a bug which requires the driver to double copy all rx packets.
