ibstat determines is_fdr10 by reading a file. That same data could just as easily be exported as a port attribute, which would make it belong to ibverbs, rather than umad. If the only point of exporting is_fdr10 from the kernel is for an ib management diag to display the value, then it's not a useful value for verbs applications. _______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
