No.  This is a Tulip-specific option to initialize the bus performance

The possible value are lightly covered in the driver comments, but only fully
documented in the Tulip manual (e.g. the 21143 Hardware Reference Manual).
There are many bitfield in CSR0, and the optimal setting is processor,
motherboard and load dependent.

The VIA Rhine likely has similar controls in the 'PCIBusConfig' register,
but the settings are not documented.
