Credit should go to Harald Welte for pointing this out to me a while
CSA is essentially a direct link to the Northbridge System Controller
(or MCH); there are some speacilized motherboards that have this
feature. So imagine a e1000 with no PCI-X bridge directly connected to
the MCH. The funny thing is it was supposed to be a cost-reduction
concept (no more PCI-X brifge). Refer to my earlier comment about
intel and its chipset division.
