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.
