		- The next three bits may be set to one of the following:
			0x00000000 : Autodetect PCI bus
			0x00000010 : Force 32 bit PCI bus
			0x00000020 : Disable parity detection
			0x00000040 : Force 64 bit PCI bus
			Default is autodetect
		- The next bit can be used to force half-duplex.  This is a bad
		  idea since no known implementations implement half-duplex, and,
		  in general, half-duplex for gigabit ethernet is a bad idea.
			0x00000080 : Force half-duplex 
			Default is full-duplex.
		- In the original driver, the ninth bit could be used to force
		  full-duplex.  Maintain that for compatibility
		   0x00000200 : Force full-duplex
