> The order of the fields in the legacy PCI header seems to get messed up in the new spec, with p. 4.1.2.5 "Legacy Interfaces: A Note on PCI Device Layout" saying:
> * Device Features 32
> * Driver Features 32
> * Queue Size 32   <-------------- !!!
> * Queue Select 16
> * Queue Notify 16
> * Queue Address 16 <------------ !!!
> * Device Status 8
> * ISR Status 8
> According to the 0.9.5 version of the spec it should be:
> * Device Features 32
> * Driver Features 32
> * Queue Address 32
> * Queue Size 16
> * Queue Select 16
> * Queue Notify 16
> * Device Status 8
> * ISR Status 8
