Hi Peter,

The bonding driver that comes with OFED 1.2 is based on the 2.6.21 upstream
kernel driver. However, we did not ported the somehow deprecated ifenslave
program which is used in SLES10 to configure bonding when you set a network
script for a bond. This means that for "IB bonds" you must not set such
script and use the mechanism in /etc/inifiniabnd/openib.conf and for "Eth
bonds" you must not use openib.conf but rather a standard network script...
Its next in our todo to provide a solution for IB bonds in the standard
framework. I am cc-ing Moni Shoua who is the OFED bonding maintainer, please
approach him and cc the list on any problem you face with the IB bonding
solution.

Or.
