| H A D | if_bgereg.h | diff 241388 Tue Oct 09 23:33:14 MDT 2012 yongari If the maximum payload size is 256 bytes or more, set the DMA write water mark to 256 bytes. Otherwise controller will encounter DMA write under run errors and would result in RX DMA hang. If the maximum payload size is 128 bytes, the water mark is set to 128 bytes as usual. While here, set maximum read request size to 2048 for BCM5719/BCM5720. For other PCIe devices, use 4096. And reprogram the maximum read request size whenever device reset is performed. |
