Since this is a 10/100/1000 interface, does "high load" mean high
relative to 1 Gb/s, or high relative to the link-level max speed? In
other words, are the bcm5700 bugs likely to be hit on a 100baseT network?
Likewise, do the hardware errata work-arounds significantly degrade
performance when the interface is used for 100baseT?
