[openib-general] [PATCH] IPoIB: Only allow root to change between datagram and connected mode

[Roland Dreier]

Change the permissions of the "mode" sysfs attribute to be S_IWUSR
instead of S_IWUGO.

FYI -- I'm planning to merge this for 2.6.21.  It doesn't seem
appropriate to allow ordinary users to mess with this sort of config.
