   ## Summary
   
   PCI endpoints cannot perform memory transactions when a bridge in their 
hierarchy has memory forwarding or bus mastering disabled. Firmware may leave 
these bits clear when handing a device over after PXE boot.
   
   Enable both bits on every parent bridge before enabling the endpoint.
   
   ## Impact
   
   fix PCI issues on intel64 hw after boot with PXE
   
   ## Testing
   
   Intel NUC with I226 NIC. After PXE boot over I226, without this changes - 
card is dead
