[openib-general] IP over IB configuration procedure

[Philippe Gregoire]

What are the requires steps to configure IP over IB ?
I was able to load the kernel modules but unable to configure the 
interface ib0 with /sbin/ifup

Is /sbin/ifup the correct command to setup the infinband interface or is 
there any other procedure to follow ?
I tried also to configure "manually" the interface but pinging another 
node does not work.

I execute the following commands :

# modprobe ib_mthca
# modprobe ib_ipoib
# lsmod
