Title:
  [i40e] LACP bonding start up race conditions

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.
