No, it doesn't seem to help. To get anything to work at all, I seem to
need to reload all the IB modules on every maching I want to use ipoib
on.

There have been two times now I've been able to see about 4 ping
packets, and then one of the arp entries seems to go away.

(On the sm machine, also the machine I am trying to ping)
10.40.5.213                      (incomplete)	ib0

(on another machine, trying to ping from..)
10.40.137.12		ether	00:00:04:04:FE:80:00C		ib0
