[Luke J Militello <Luke@xxxxxxxxxxxxxxxxx>]

I'm having a similar issue running 12.04 with the Trusty hardware
enablement stack; kernel v3.13.  I have the MCP51 controller and get
random protocol flaps even with the physical link still up.  This causes
problems as I have an NFS auto mounted home directory.  My only
workaround has been to spawn a root shell on tty1 and reboot.  In
comment #6, when you say reset, are you referring to bouncing via
ifconfig or reloading forcedeth?  The next time this happens to me, I
will try both and see what happens unless anyone else can comment on
this issue with a workaround.

Title:
  forcedeth autoneg for 100M-FD fails

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Wired network on this laptop fails to come up automatically on the
  work network.

  After running this ethtool command, the wired network works, until the NIC gets turned off (say, suspend):
  ethtool -s eth0 speed 100 duplex full autoneg off

  Running the ethtool command above gives this info in dmesg:
  [   62.560356] forcedeth 0000:00:0a.0 eth0: link up
  [   62.560527] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
