ib_ip2pr is not needed for normal operation.  modprobe ib_ipoib should 
pick up all the dependencies (if you have the modules installed in 
/lib/modules/`uname -r`)

Yup.

It also depends what pkey your subnet manager uses for the IP network. 
Sun's setup uses pkey 0x8001, so I need to setup a virtual NIC using the 
ipoibcfg command.
