Title:
  [PATCH] r8169 writes to memory not assigned to the device

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The following applies to the 3.13 in trusty.

  When transferring data at >= around 100Mbps, the IOMMU logs errors such as:
  AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x001c address=0x0000000000003000 flags=0x0050]

  I have locally cherry-picked 7a9810e7bd99: r8169 "Enable RX_MULTI_EN
  for RTL_GIGA_MAC_VER_40" to the Ubuntu-3.13.0-37.64 kernel and
  confirmed this fixes the issue for my card as well.  Please consider
  this for backporting to the 3.13 stable tree.

  The hardware is:
