Title:
  i40e: Setting VF MAC address causes General Protection Fault

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released
Status in linux source package in Disco:
  Fix Released
Status in linux source package in Eoan:
  Fix Released
Status in linux source package in Focal:
  Fix Released

Bug description:
  [Impact]
   * Creating SR-IOV enabled VMs in Openstack can sometimes trigger the GPF and 
leave system unusable

  [Test Case]
   * Continuously spin up VFs and set MAC address with e.g. ifconfig

  [Fix]
   * The fix updates the VSI pointer passed down to i40e_set_vf_mac function() 
if the adapter is still in reset, preventing the GPF.

  [Regression Potential]
   * Regression potential should be low, as we're now updating the VSI using 
the ID stored in the VF pointer
   * Regressions could arise from issues in VF creation or reset, as that would 
corrupt the new VSI pointer
   * Patch was validated and tested in a production environment
