  14e4:165f tg3 eth1: transmit timed out, resetting on BCM5720

Bug description:
  we have a problem with Dell PowerEdge machines, having the Broadcom
  5720 chip. We have this problem on generation 12 systems, across
  different models (R420, R620), with several combinations of bios
  firmwares, lifecycle firmwares, etc... We see this on several versions
  of the linux kernel, ranging from 3.2.x up tot 3.11, with several
  versions of the tg3 driver, including a manually compiled latest
  version (3.133d) loaded in a 3.11. The latest machine, where we can
  reproduce the problem has Ubuntu Precise installed, but we also see
  this behaviour on Debian machines. We run Xen on it, running HVM hosts
  on it. Storage is handled over iSCSI (and it is the iSCSI interface we
  can trigger this bug on in a reproducible way, while we have the
  impression it also happens on other interfaces, but there we don't
  have a solid case where we have e reproducible setup).

  All this info actually points into the direction of the tg3 driver
  and/or hardware below it not handling certain datastreams or data
  patterns correctly, and finally crashing the system. It seems
  unrelated to the version of kernel running, xen-version running,
  amount of VM's running, firmwares and revisions running, etc...

  We have been trying to pinpoint this for over a year now, being unable
  to actually create a scenario where we could reproduce this. As of
  this week, we finally found a specific setup where we could trigger
  the error within a reasonable time.

  The error is triggered by running a certain VM on the Xen stack, and
  inside that VM, importing a mysqldump in a running mysql on that VM.
  The VM has it's traffic on an iSCSI volume, so this effectually
  generates a datastream over the eth1 interface of the machine.  Within
  a short amount of time, the system will crash in 2 steps. We first see
  a timeout on the tg3 driver on the eth1 interface (dmesg output
  section attached). This sometimes repeats two or three times, and
  finally, step 2, the machine freezes and reboots.

  While debugging, we noticed that the bug goes away when we disable sg
  offloading with ethtool.

  If you need any additional info, feel free to ask.
