  commit 7b8052e19304865477e03a0047062d977309a22f
  Author: Jan Beulich <JBeulich@xxxxxxxx>
  Date:   Mon Oct 19 04:23:29 2015 -0600
  
      igb: fix NULL derefs due to skipped SR-IOV enabling
      
      [ Upstream commit be06998f96ecb93938ad2cce46c4289bf7cf45bc ]
      
      The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
      during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
      right number of queues") causes VFs no longer getting set up, leading
      to NULL pointer dereferences due to the adapter's ->vf_data being NULL
      while ->vfs_allocated_count is non-zero. The first commit not only
      neglected the side effect of igb_sriov_reinit() that the second commit
      tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
      without which igb_enable_sriov() is effectively a no-op. Calling
      igb_{,re}set_interrupt_capability() as done here seems to address this,
      but I'm not sure whether this is better than sinply reverting the other
      two commits.

  commit 7b8052e19304865477e03a0047062d977309a22f
  Author: Jan Beulich <JBeulich@xxxxxxxx>
  Date:   Mon Oct 19 04:23:29 2015 -0600
  
      igb: fix NULL derefs due to skipped SR-IOV enabling
      
      [ Upstream commit be06998f96ecb93938ad2cce46c4289bf7cf45bc ]
      
      The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
      during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
      right number of queues") causes VFs no longer getting set up, leading
      to NULL pointer dereferences due to the adapter's ->vf_data being NULL
      while ->vfs_allocated_count is non-zero. The first commit not only
      neglected the side effect of igb_sriov_reinit() that the second commit
      tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
      without which igb_enable_sriov() is effectively a no-op. Calling
      igb_{,re}set_interrupt_capability() as done here seems to address this,
      but I'm not sure whether this is better than sinply reverting the other
      two commits.
