Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On Ubuntu 12.04.1 LTS

  With the following networks settings:

  /etc/network/interfaces
  auto lo
  iface lo inet loopback

  auto eth0
  iface eth0 inet dhcp

  # Network: instances
  # Bonding
  auto eth2
  iface eth2 inet manual
      bond-master bond0
  auto eth4
  iface eth4 inet manual
      bond-master bond0

  auto bond0

      bond-mode 802.3ad
      bond-miimon 100
      bond-lacp-rate 1
      bond-slaves none

  The RX packets drop counter increase very fast:
