  ##### Steps for reproduce #####

  This is my /etc/network/interfaces file:

      auto lo
      iface lo inet loopback

      auto openibd
      iface openibd inet manual
              pre-up /etc/init.d/openibd start
              pre-down /etc/init.d/openibd force-stop

      auto bond0
      iface bond0 inet manual
              pre-up ip link add bond0 type bond || true
              pre-up ip link set bond0 down
              pre-up ip link set bond0 type bond mode active-backup arp_interval 2000 arp_ip_target 10.36.0.1 arp_validate 3 primary eno1
              pre-up ip link set eno1 down
              pre-up ip link set eno1d1 down
              pre-up ip link set eno1 master bond0
              pre-up ip link set eno1d1 master bond0
              pre-up ip link set bond0 up
              pre-down ip link del bond0

      auto vmbr0
      iface vmbr0 inet static
              address 10.36.128.217
              netmask 255.255.0.0
              gateway 10.36.0.1
              bridge_ports bond0
              bridge_stp off
              bridge_fd 0

  I execute these commands:

      wget http://dl-cdn.alpinelinux.org/alpine/v3.7/releases/x86_64/alpine-virt-3.7.0-x86_64.iso -O alpine.iso
      qemu-system-x86_64 -machine pc-i440fx-xenial,accel=kvm,usb=off -boot d -cdrom alpine.iso -m 512 -nographic -device e1000,netdev=net0 -netdev tap,id=net0

  And after few moments I have hang kernel, and theese messages in
  console:

      [74390.187908] mlx4_core 0000:11:00.0: bond for multifunction failed
      [74390.486476] mlx4_en: eno1d1: Fail to bond device
