My guess is part of the bring up scripts to load the drivers write a node description value to a file, which is seen by the HCA driver. For example, on a system running kernel.org 2.6.34-rc7 the node_desc that I see is: MT25208 InfiniHostEx Mellanox Technologies If I write to the node_desc file, the description changes as expected. However, if I unload then reload the driver, the node_desc is reset. -Sean _______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
