82559 prefetches the next command

[Kallol Biswas]

Hi Donald,
           I have very little knowledge about 82559 card and
network programming. I was just reading your driver(not the latest one 
I believe). 82559 prefetches the next command , won't there be 
any problem if it prefetches the next command before the driver
sets it up? Question is what happens when the CU executes a command
with invalid parameter, does it die? How do you determine that
what fault it has encountered? By looking at Port Dump/Command
dump registers? Is there any data manual for 82559's internal 
micro machine registers like we have for most of the SCSI IO 
cards?

A quick reply is greatly appreciated.

Thanks,
Kallol
