it was pointed out on the list that ixgbe was failing when using 64kB pages and large 16kB MTU. since with a 64kB PAGE_SIZE MAX_SKB_FRAGS = 3, the way the driver was configuring page usage was assuming 2kB is half a page, and was only ever dmaing that much data to a half page. (16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to 16kB for each descriptor.
