In that case I propose to change "Linux network stack" into "Linux network driver" - that's all what the rxe driver uses from the network stack, and there is more in the Linux network stack than only the network drivers. >> + standard Ethernet adapter to interoperate with a RoCE >> + adapter or with another system running the RXE driver. >> + Documentation on InfiniBand and RoCE can be downloaded at >> + www.infinibandta.org and www.openfabrics.org.

Thanks. Maybe it's a good idea to mention also that while RoCE benefits from a lossless converged Ethernet network, that the protocol also works over a regular (not lossless) Ethernet network.
