Power Systems Ethernet Port Attributes

I found a useful attribute chart for the set of Ethernet adapters for IBM Power Systems servers I would like to share.  Like if you find this useful.  It is a little wonky as it stands.  I am still on a learning curve for getting things to work in these blogs.  A spreadsheet version of this can be found here:
