Title:
  openssh client ignores -o Tunnel=ethernet option, creating an IP
  tunnel device instead of an ethernet tap device

Status in openssh package in Ubuntu:
  Confirmed

Bug description:
  This is a regression from the version of the client in 14.04 compared
  to 13.10. I'm connecting to 12.04.4 for a server.

  Expected behaviour:
  Creating a connection with the option "-o Tunnel=ethernet" will create a layer2 ethernet tap device.

  Actual behaviour:
  New client creates a  layer3 IP tunnel.

  The old version of the client that works properly (installed manually on 14.04):
  OpenSSH_6.2p2 Ubuntu-6ubuntu0.3, OpenSSL 1.0.1f 6 Jan 2014

  The new version of the client that does not work properly:
  OpenSSH_6.6p1 Ubuntu-2ubuntu1, OpenSSL 1.0.1f 6 Jan 2014

  The version of the SSH server I'm connecting to:
  openssh-server:
    Installed: 1:5.9p1-5ubuntu1.3
    Candidate: 1:5.9p1-5ubuntu1.3
