Next time you hear one of these stories from Just having controllers made with standard chips does not ensure that they are within specification. I don't remember the details of the LANCE chip, but the Intel 82586 can be configured to violate just about every parameter you might think of. The interpacket spacing is one such parameter. The parameterization makes it useful for implementing different speed networks (like Starlan) with the same chips. So, even though Sun's products are made with standard parts doesn't guarantee that someone hasn't changed parameters to something non-standard.
