Comment 1 Doug Ledford 2010-01-28 12:09:32 EST
IB bonding is enabled in the 2.6.32 kernels.  However, we do *not* use an ib-bonding package like OFED does.  OFED does that merely to deliver a modified core bonding module for kernels that don't already support IB bonding.  Since we do, that package is not necessary.  Setting up ib bonding is done the same is it is done for ethernet interfaces, via the /etc/sysconfig/network-scripts/ifcfg-ib? files.  Only failover mode bonding is support, this is a limitation of the IB hardware.
