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.
