Because I need some way of showing there are 3 hypertransport links. With just one I don't have enough places to hang the devices off of. > Another question maybe related to the former one is, in "device" structure > what does the "link[MAX_LINKS]" and "links" member describe? > Does "link[MAX_LINKS]" describes the secondary or subordinate bus of a bridge > device? > Why MAX_LINKS is defined to 3? Because that is the largest number of links I have ever had hanging off of one device.
