Hi Hal
One TODO we have found is that in order to guarantee traps can
be delievered to the SM - it would have been nice if light sweep
will use LID routing and not direct routing. This way the LFTs could
be verified or else a heavy sweep conducted.
This patch only changes the TODO file so we do

Are you ignoring compile warnings about class_device_create()? Since
2.6.15 is out, the OpenIB svn does not support 2.6.14 any more, so you
may run into problems like this.
You will probably need to restore the compatibility hack removed in
r4784 by adding something like
#include
Or Just to make sure, would the __be64 node_guid field of struct
Or ib_device have the exact semantics of the __be64 node_guid
Or field of struct ib_device_attr ? iser uses it from the attr
Or struct and we can sure move to use it from the device struct.
Yes, that's right.
