  By triggerring the VF reset from PF reset,

        echo 1 > /sys/bus/pci/devices/PF-BDF/reset

the PCI bus master bit will cleared on VF, so the VF needs to enable
this bit before restart.

This patch set adds the API to enable PCI bus master.

v5: error handling if bus master enable failed
v4: change the API to set type, so can enable or disable
v3: added the missed annotate symbol add time
v2: rebase to new librte directory path

Haiyue Wang (3):
  bus/pci: set PCI master in command register
  net/iavf: enable PCI bus master after reset
  net/i40e: enable PCI bus master after reset
