Subject: Re: [PATCH 2.6.19-rc1] ehca firmware interface based on Anton Blanchard's new hvcall interface
> - shca->ib_device.node_type = RDMA_NODE_IB_CA;
> + shca->ib_device.node_type = IB_NODE_CA;
My mistake, I tested against Paul's git tree only and then used a wrong patch script,
which exchanged those defines.
This time I did all manually and tested also against your git tree with Anton's patch
http://ozlabs.org/pipermail/linuxppc-dev/2006-July/024556.html.
Thanks!
