Title:
  e1000e module signals that interface is up

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  VERSION
  =======
  Ubuntu 12.04.5 LTS
  Linux 3.8.0-23-generic
  Ethernet controller: Intel Corporation 82574L Gigabit Network Connection
  Network kernel module: e1000e

  STEPS TO REPRODUCE
  ==================
  Connect two machines (without switch); nodeA and nodeB.
  nodeA is a machine as specified above.
  nodeB can be a machine using the e1000e module or igb module (these are the ones we have in our lab).

  Verify that interfaces are up and that you have connection between
  nodeA and nodeB.

  Bring interface down:
  root@nodeA:~# ip link set dev ethX down

  Quickly check interface on nodeB:
  root@nodeB:~# ip link show dev ethX
  5: ethX: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 10000

  Wait ~2s and check interface on nodeB again:
  root@nodeB:~# ip link show dev ethX
  5: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 10000

  ACTUAL RESULTS
  ==============
  Interface ethX on nodeB comes up after ~2s.

  EXPECTED RESULTS
  ================
  Interface ethX on nodeB should not come up again. It should remain down.

  ADDITIONAL INFORMATION
  ======================
  This issue has been reproduced with kernel 3.14.5 (Ubuntu 14.04).
  This issue can *NOT* be reproduced on two machines using the igb kernel module.
  This issue is reproducible with Linux 4.2.3.
