Title:
  JMicron JMC250 ethernet: networking always disconnected

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Summary:
  Ubuntu version: 14.04 desktop x64
  Problem hardware: JMicron JMC250 ethernet controller (jme drivers)
  Expected behavior: Ethernet networking works when cable connected.
  Actual behavior: Networking always shows "disconnected", even when cable connected.

  Details:
  In Ubuntu 14.04 with a JMicron JMC250 ethernet controller, the ethernet link is always shown as "disconnected", even when the cable is connected and networking is otherwise working.

  In Ubuntu 12.04, this same ethernet controller also exhibited the same
  problem.  However it was fixable by downloading and manually compiling
  a new version of the jme drivers from here:
  ftp://driver.jmicron.com.tw/Ethernet/Linux/jmebp-1.0.8.5.tar.bz

  In 14.04, the above 1.0.8.5 driver no longer compiles and is thus not
  installable.

  I tried downloading and compiling the latest source for the driver
  from
  https://github.com/torvalds/linux/blob/master/drivers/net/ethernet/jme.c.
  This driver does compile, but after installation still doesn't work,
  with the wired network status always showing "disconnected".

  There is a related Launchpad bug #880316 but that one is for *missing*
  drivers in an older Ubuntu version, not *broken* drivers.  (The
  drivers are now included in 14.04, but are totally broken.)

  These drivers haven't worked out of the box since 2012... can we get a
  little love here?
