NetEffect cards have iWARP drivers in OFED and RoCEE is not supported by NetEffect cards.

As I understand it, Soft-RoCEE is only to allow developers to run InfiniBand VERBS over Ethernet cards that do not have native RoCEE drivers. The latter requires RDMA and CEE, whereas Soft-Rocee does not have these dependencies. The NetEffect and Mellanox cards both have RoCEE drivers in OFED and these should be used in preference. The maintainers will accept bugs on these.
Soft RoCEE is not currently included or maintained by OFED and is maintained separately by systemfabricworks

Hi Mr Lee,
I will respond off list since rxe is not technically part of OFED.

Dear all,
I have installed the OFED-1.5.2-rxe on our linux host, which has three network interfaces, Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet NIC, Mellanox Technologies MT26478 [ConnectX EN 40GigE, PCIe 2.0 5GT/s] and NetEffect NE020 10Gb Accelerated Ethernet Adapter (iWARP RNIC). The Soft-RoCE can work on the first two cards, but when I applied the Soft-RoCE to the Neteffect card and use "ibv_devinfo" to view the RDMA device, I got following errors on some of the hosts in our cluster, and the whole OFED stack doesnot work.

However, some hosts in our cluster can make Soft-RoCE work on the iWARP RNIC with the same configuration. The info is as follows,

The two host are identical. The system info is as follows,

So, my question is why is that Soft-RoCE does not work on some of the NetEffect iWARP RNIC's, but does work on the other NetEffect iWARP RNIC's? All iWARP RNIC's are on different hosts of the same cluster, and connected via a Juniper EX 2500 switch.
Any help will be greatly appreciated.
