Calculate the VIP2 PCI bus bandwidth on a 7500. All this means in this
context is that this implementation is interoperable with other GIG-E
implementations (for some definition of implementation, see CLNS large MTU
and jumbo frame issues).
The card is limited by the PCI bus. It is still a gig-E board, it just
can't go wirespeed.
