I am as close to 100% confident about > that as I am with anything. You are correct DSS-G have always used OFED drivers. However the interface name change between stock drivers and OFED drivers that now exists throws a massive spanner in the works. Basically it means you can't have xcat (or anything else for that matter) setup the networking at install time as you could previously which sucks. I spent much of Sunday developing a shell script that nukes the network configuration from on top and sets it all up using nmcli. However it can't be run till after the install, and even then I have to put the ports back into ethernet mode and reboot first. As time passes I grow nostaglic for the days when everything was ethX.
