From b26f9b9949013fec31b23c426fc463164ae08891 Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Thu, 1 Apr 2010 17:08:41 +0000 Subject: RDMA/cma: Pass QP type into rdma_create_id() The RDMA CM currently infers the QP type from the port space selected by the user. In the future (eg with RDMA_PS_IB or XRC), there may not be a 1-1 correspondence between port space and QP type. For netlink export of RDMA CM state, we want to export the QP type to userspace, so it is cleaner to explicitly associate a QP type to an ID. Modify rdma_create_id() to allow the user to specify the QP type, and use it to make our selections of datagram versus connected mode.
