Bug description:
  [Impact]
  There is a USB Ethernet port, 0bda:8153, on Dell IE Docking.
  After plugged in the docking, system hard hangs.

  [Fix]
  This issue has been fix after v4.11-rc4, so after bisecting the kernel, we 
found the first bad commit, and realized this issue is from Realtek USB 
Ethernet driver with a non-initialized list.
 98d068a r8152: fix the list rx_done may be used without initialization

  [Test Case]
  Verified on the Dell XPS and IE docking, and confirm this patch works.

  [Regression Potential]
  It's a one line patch and do the initialization of the list variable, there 
should be no any regression would be resulted from this.

[Kleber Sacilotto de Souza]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]
  There is a USB Ethernet port, 0bda:8153, on Dell IE Docking.
  After plugged in the docking, system hard hangs.

  [Fix]
  This issue has been fix after v4.11-rc4, so after bisecting the kernel, we 
found the first bad commit, and realized this issue is from Realtek USB 
Ethernet driver with a non-initialized list.
 98d068a r8152: fix the list rx_done may be used without initialization

  [Test Case]
  Verified on the Dell XPS and IE docking, and confirm this patch works.

  [Regression Potential]
  It's a one line patch and do the initialization of the list variable, there 
should be no any regression would be resulted from this.

r8152: fix the list rx_done may be used without initialization

The list rx_done would be initialized when the linking on occurs.
Therefore, if a napi is scheduled without any linking on before,
the following kernel panic would happen.
