Title:
  Ubuntu 14.04 bonding slaves stay down after boot

Status in ifenslave-2.6 package in Ubuntu:
  Confirmed

Bug description:
  Hello, this is an Ubuntu 14.04.1 LTS server with kernel 3.16.6,
  setting up a bond of two 40 GbE NICs (Mellanox with the lastest OFED).
  Looks ike no matter what the order of the slaves is in
  /etc/network/interfaces, the bond does not bring these up:

  Best regards, Alex Gorbachev
