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.

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