On any platform running Red Hat Enterprise Linux 10 and configured with any of the HPE network adapters listed in the Scope section below, the configuration of the Remote Direct Memory Access (RDMA) protocol will fail when using the following command syntax to load the qed driver with a port interface PCI ID (xx:xx.x) and a RDMA protocol value (p):#modprobe -v qed rdma_protocol_map=<xx:xx.x>-<p>The RDMA protocol (p) values are as follows:0 — Accept the default (RoCE)1 — No RDMA2 — RoCE3 — iWARPFor example, to change the interface on the port given by 04:00.0 from RDMA over Converged Ethernet (RoCE) to Internet Wide Area RDMA Protocol (iWARP), the following command can be executed:#modprobe -v qed rdma_protocol_map=04:00.0-3The output of transport in ibv_devinfo can still be seen as"InfiniBand (0)".
