flexboot versions?

Hello all,

I am trying to install flexboot on two HT26428's. The most recent version of flexboot I can install for my FW version is 3.4.124, but there seem to be 3 different versions (VPI, ethernet, and infiniband). I am using them as infiniband ports, but I was just wondering if I need just the IB package or the IB package and the VPI package?

Thanks,

Trevor
